Recommendation for new Clojure learners: the Coursera Algorithms Specialization

I just finished the 4-class (16 weeks total) Algorithms Specialzation from Coursera. Prior to this, the only real Clojure I had written was in solving Project Euler problems. I felt like this would give me something more substantive to learn, and I was right (more so than I expected).

I found it very challenging, figuring out how to implement algorithms like QuickSort or Dijkstra's shortest path in a functional paradigm with immutable data structures. I have a B.Sci. in software engineering, but I've been out of school for nearly 30 years. I assumed (!) that this would be mostly a review of the algorithms study I had done in college. It turned out to be much more in-depth than what I had done so long ago. So not only did I get to push myself into more substantive Clojure development, I also learned a lot of material that was new to me. As a bonus, there were several of the programming assignments that ended up being flat-out EASY to implement in Clojure, given that maps, sets, etc. are all first-class types. And most of the Clojure solutions were very short and compact.

Overall, I feel like I got a lot out of this series of classes, and really extended my grasp of FP in general and Clojure in particular.

(Note: the classes do require a monthly subscription fee. I am not affiliated with Coursera in any way or form, and I do not benefit from anyone subscribing to these classes.)

Help set up or join a local study group for algorithms and data structures ?

Hi all -

I'm looking at signing up for the Algorithms Specialization on Coursera (https://www.coursera.org/specializations/algorithms).

As a self-taught programmer, I have a gap in my computer science fundamentals that I'm trying to fill, and this set of courses seems like a good way.

Are you interested in doing the same and setting up a weekly local study group? I'm thinking up to around 5 people who could get together for two hours, two times per week at a cafe, library, coworking space, something like that.

I know that I'm more likely to complete the courses, and have an easier time getting through them, if I'm doing it with some peers. The course takes 4 months if you're doing 7 hours a week - we might move more quickly if the group is up for it.

Learn the 4 principles of Object Oriented Programming, and also the SOLID principles. And practise them. Write OOP code just for the purpose of using those principles.

I assume you learned Data Structures & Algorithms (DSA) in your masters degree? Trees, Binary Search Trees, Hash Tables, Sorting algos, Search, Shortest path, etc. If not: https://www.coursera.org/specializations/algorithms

If you did learn DSA, use Leetcode to practice coding problems. This is the website for CS professionals to practice tech firm interview-style problems, and general coding problem practice.

Which Specialization is more suitable?

TLDR;

Which coursera specialization is better for algorithms and data structures (Standford's or UCSD's)

Hello there,

I'm currently a first year computer engineering student, almost finished my first year though, I took two programming languages courses this year (I had no prior knowledge), I took both MATLAB and C++ both courses that had some advanced concepts like OOP,Polymorphism ,I didn't take separate algorithms or data structures courses,they aren't taught in my college as separate courses -I guess- I might be unaware of the syllabi though, I prefer self learning anyways, however I'm planning to study them this summer, so I found two coursera specializations and I'm hesitated which one would be more suitable.

However those are the links for reference, and advice is always appreciated! , And thanks in advance! :)

I think that this course would be a great introduction:

Introduction to Computer Science and Programming from MITx.

syllabus.

It is a very involved course and covers a lot of ground, but it has more focus on the things are important to building strong foundations when compared to CS50. CS50 does things like throws external sources at you and says here this is web development and this is cyber security. When they introduce it to you, you don't have the background to understand the context of what you are reading, and you keep yourself busy without effectively learning. One of the pitfalls of being a beginner is mistaking being busy for being productive.

After I learned basic programming I went through this MOOC series: Algorithms from Tim Roughgarden on coursera.

It was super challenging but really built my programming chops because I had to learn how to "think like a computer scientist" by mastering control flow, imperative programming, and the effective representation of data. Then you need to learn how to deal with larger software projects. That's the stage I am on.

My recommendation is Tim Roughgarden's Algorithms Specialization at Coursera. It's structured, Roughgarden is a very good teacher, and you'll actually learn the fundamentals you need to solve problems. It's about ~160 hours total if you're a total beginner, so it's 1-2 months if you're working hard.

A lot of people here are recommending CLRS. I wouldn't use it even though I've worked through it at various points over the last year and my algorithms course was taught in it. It's focused on the mathematical analysis rather than practical understanding and implementation of algorithms. You can use it for that, but that's not the intended audience of the book.

CPEN 221 is very similar to MIT’s Software Construction course. You can get a headstart if you work through some of that. Bonus: it’s also one of the most applicable courses to actually working as a software engineer, so you can get a small sense of whether you might like that career path.

I’d also recommend looking at an algorithms class. Stanford’s is good. This will help you in software interviews and CPSC 221.

In general CPEN is a lot of learning how to learn. You’re not expected to know Java before 221 but you should be okay with it by the end of September. You don’t need to know anything about hardware but you’ll have built a toy processor in Verilog by the end of second year. This is also the way it is on the job: you don’t need to know any of them before you start, but you might work in 4 different languages in the span of a 4 month co-op.

Maybe getting started with Algorithms and Data Structures would be the best way to go. Since you already know the basics of Python, you can start by doing this Stanford University Algorithms course from Coursera.

Coupled with these, starting out with solving basic algorithmic problems at Hackerrank / Codechef should be a good way to go.

All the best!

do you have a solid math background? not that you 'need' it persay, but it would make it a little easier. this is prob the best course ive ever taken, but it gets a little math heavy at times, some people like learning the actual proofs of the algorithms. not just learning the algorithm but why it works the way it does, why its correct etc...you can always skip those videos though

Stanford algorithms

4 courses. different paradigms in each. divide and conquer / greedy/ dynamic programming...also teaches many diff data structures. its challenging, but give it a try. see how you like it. hes an excellent teacher.

Programmers of r/India , I need advice on which Algorithms courses to recommend to a friend(I have a list of em)

This two part course from MIT OCW

1) Introduction to Algorithms

2)Design and Analysis of Algorithms

The NPTEL course by Naveen Garg

1) Data structures and Algorithm

These two Princeton courses from coursera.

1) Algorithms part 1

2) Algorithms part 2

These two Stanford Algorithms courses.

1) Algorithms design and Analysis 1

2)Algorithms design and Analysis part 2

The above two courses are available as a 5 part course in coursera

So which of these should I ask him to complete? He said he is learning some python(I don't know how proficient he is in it) and wants to learn machine learning.(I think he is being bit naive in thinking learning ML without a good DSA base)

I also want to know the websites where you can do code challenges that may or may not get you a Job interview(I know about Hackerrank but nothing else).

He has asked me some advice on this as I was interested in learning programming a while back(I have given up on it for now).

What are the things he should learn at the very least to get a entry level job. He has been in TCS for nearly 3 years as a support guy. Two main things.

1) Anything else you guys recommend he should do?(as in like an intro to programming like CS50 or the MIT intro to programming with python)

2) How should he progress?(as in the sequences of courses one should do)

3) How long would it reasonable take to cover said courses?(as he is working right now)

Algorithms Part 2 still not open - any alternatives?

The course page was created in Coursera more than two months ago. Originally it is said to be starting in October 2016 but still hasn't after two months. Now the page says it will start in December 2016, but again, still waiting. I have completed Part 1, and some classmates said the constant delay is due to Coursera's policy of shifting to purchase-only courses. So I am not even sure if the course will ever begin.

Are there any good alternatives to learn about algorithms? I heard about the Stanford course but unfortunately it is now purchase-only.

Or should I just wait and start the next course on Functional Programming/Scala first? I assume it won't require specific knowledge from that particular Algorithm course?

Thanks!

Thanks for the response. Not from the US sadly.

The most widely recommended and exhaustive course I've found is this specialization course on Coursera, which is a specialization track made up of 4 DS&A courses.

In terms of accreditation it seems it might not carry much ballast, but do you reckon it might reflect more willingness to independently learn and plug in gaps.

Thanks again, now I understand the use of learning data structures and algorithms to become an efficient developer Algorithms specialisation by Stanford will this course cover everything I need to understand data structures and algorithms? Or would this be an overkill. There is an another course offered by Princeton uni but it looks like there's only a part of it available online.

Coursera has classes from both Princeton and Stanford that cover the material to a level expected from a CS undergrad (e.g. their Algorithms track).

I took the Stanford courses some time ago and they were extremely helpful for someone with no formal CS background. They do represent quite a bit of time commitment (if you want to do more than just watch the lecture videos), but they are free.

Verstehe. Also ich will dir auch nicht C++ aufschwatzen. Es kommt natürlich darauf an, was du so lernen möchtest. Sprachen wie C++ bieten sich gut dafür an so Datenstrukturen und Algorithmen zu lernen, weil sie dich relativ nah an den Speicher lassen. Wenn dich das interessiert, kann ich sie dir empfehlen. (Wobei es auch nicht unmöglich ist das mit anderen Sprachen zu lernen.)

Was die Länge der Bücher angeht hast du natürlich recht. Das wirkt erst mal ernüchternd. Aber wie gesagt, es ließt sich schneller als man denkt. Die hohe Seitenanzahl kommt schon allein deswegen zusammen, weil viel Code gedruckt ist. In dem ersten Buch sind nach jedem Kapital (ca. 50 Seiten) auch Übungen mit dabei, die machen solltest. (Der Author sagt eindeutig, wer die Übungen nicht macht, hat das Buch nicht gelesen.) Das lockert das ganze sehr auf und macht Spaß. Ich habe damals im Studium jeden Abend ein Kapital gelesen und danach die Übungen gemacht. War nach 6 Wochen oder so durch. Danach hast du halt ein solides Fundament. Soweit ich mich erinnere war auch kein Kapitel überflüssig oder zu komprimiert geschrieben.

Für Algorithmen kann ich den Kurs von Tim Roughgarden empfehlen. Ansonsten lohnt es sich wirklich auf Websites wie HackerRank die Probleme zu lösen. (Du schreibst ein Programm und die Website checkt dann ob es anständig und effizient läuft.) Das ist ein super Spaß und Coding Interviews sind danach ein Witz.

I don't know how you did 106A, but it's followed by 106B and 161. Note that 161 has a Coursera version (each individual course is free, don't buy the specialization) simply called Algorithms and that although on-campus it requires 103 and 109 beforehand, you can likely get away with not taking a Discrete Math course because the Coursera version covers necessary math as needed.

See, the thing is, when you're actually working, you probably only think about CS concepts like 1% of the time. A lot of people slowly forget after graduating college, but as long as you remember the idea behind then, you can look it up.

If you want to see what a top company like Google recommends studying: https://careers.google.com/how-we-hire/interview/#interviews-for-software-engineering-and-technical-roles If you can recognize all the terms in this list, that's a good place to be. If you can actually describe everything, even better.

I recommend taking some free online courses like on Coursera. Example:
https://www.coursera.org/learn/cs-algorithms-theory-machines
https://www.coursera.org/specializations/data-structures-algorithms
https://www.coursera.org/specializations/algorithms

The courses might teach you a little bit about hardware, but you can skip those if you want.

edit: If these courses aren't free, look around on other sites. There are even plenty of videos on youtube if you know what to search for.

I’m currently an undergrad majoring in Computer Science and Physics, so hopefully I can lend some helpful info.

As far as the typical math sequence is concerned, we do Algebra 1, Geometry, Algebra 2, PreCalculus, Calculus 1 (AB), Calculus 2 (BC), Calculus 3 (Multivariable) in that order starting from Algebra 1 in 7th/8th grade.

I’m not sure how far you’ve done math. You said till Geometry, so in that case, you would technically need to know Algebra 2 and PreCalculus before you start any Calculus.

I would highly recommend Professor Leonard on YouTube (https://m.youtube.com/channel/UCoHhuummRZaIVX7bD4t2czg). Go to his YouTube channel and click on Playlists at the top. He has complete video playlists for Calculus 1, 2, AND 3. He also has playlists for PreAlgebra, Intermediate Algebra, and PreCalculus, but they’re not complete like the Calculus ones. Focus on the playlists that say full-length videos as those are usually the best. Keep in mind though that his videos are pretty long - 2-3 hours each. However, he is the only reason I survived Calculus in college. He’s an absolutely phenomenal teacher. So if you want to master calculus, I highly recommend Professor Leonard.

Other than that, you also have KhanAcademy which is a pretty good (if not in depth) resource to at least get a idea of the topics in every course. You could maybe do Algebra 2 and PreCalc through KhanAcademy (supplementing with Leonard as needed) and use Professor Leonard more for the higher math like Calculus. Or if you want and I think this should be ok: you could just try watching from the beginning of Leonard’s Calculus 1 (Full length vids) playlist. He starts out pretty basic. See if you understand like the first 4 vids. If not, then do Algebra 2 + PreCalc like I mentioned before.

You could also do courses through edX, Coursera, and udemy, which all have very good online courses. I’ll put some recommendations below to help you get started.

As far as “CS math” is concerned, that generally means discrete mathematics and Algorithms. In general, you don’t really need like PreCalculus or Calculus for this. However, you need a decent amount of basic mathematical maturity to be able to handle the complexity of an in depth Algorithms course which is why in a sense you kind of should do it.

So, in general, I would first recommend building some basic math maturity i.e. maybe till or through Calculus 1 to get yourself ready. And then, I would recommend doing some of the CS specializations through Coursera to acquire more of a formal CS background with respect to Discrete math, Algorithms, and Data Structures. I’d recommend doing all the courses in the following specializations:

  1. https://www.coursera.org/specializations/algorithms

  2. https://www.coursera.org/specializations/data-structures-algorithms

Later on, you could also look at courses on AI, Machine Learning, and Deep Learning. Coursera has some great courses for these topics.
