IBM ILOG CPLEX Optimization Studio Reviews

I use CPLEX to solve integer programming formulations. I think the performance is good. We can use it solve many problems, and it did. 

I think we can code quickly. I used C++ before, it would take me a long time to code in the platform. But I can really code in CPLEX easily, and I can solve problems quickly.

It's easy to read, it's easy to code.

Not me, but my group members published high-quality papers relying on CPLEX.

We really use CPLEX to get the exact optimal solutions. But for other algorithms, we can just get approximately optimal results.

Compared with C++, which I used before, for larger transportation networks, CPLEX will take a longer time. For the shorter ones, it's very quick.

I didn't use tech support.

I think it is easy to do.

If I had a friend at another university and they had the same problem as me or a similar formulation as me, just integer programming, if CPLEX can be used to solve those problems, I would introduce CPLEX to them.

My primary use case was for a class that I've taken in integer programming where it required us to implement some basic models in CPLEX. It performed really well. It was a little bit difficult to get at the beginning. What was difficult was setting the sets into it, sets of variables.

The best thing is that it offers, compared to other programs that I've used - LINDO and LINGO - it gives you much control on the parameters and the sets, so you can do a lot more with CPLEX.

It helped me because it was just easier to implement complex models. That's it. But if it was a basic model, then I would use another program. It's not worth the complexity.

The layout of the program, the way the windows appear. It's kind of confusing at the beginning to get a hold on.

Great. It never crashed. No lag time.

I didn't implement any complex models in it, but I feel if I were to do that, I would use CPLEX for sure.

I didn't use it, except at the beginning. Licensing stuff. That was OK.

LINDO and LINGO.

I wasn't involved in setting it up.

From my experience, it's the best out there for complex models.

I need to do searches, solve mathematical modeling and obtain exact solutions, so I need to use CPLEX to obtain the exact solutions. I usually use CPLEX, but sometimes I use metaheuristics, and I use CPLEX to compare with metaheuristics. It is very convenient and very easy for me. 

It performs very well but because I'm not very familiar with it I still need to learn more about it.

It is easy to use compared to other software, like Lingo.

I would like for them to offer a free version. We have to use the version that we got from my teacher but sometimes it doesn't work. 

I would also like for there to be more tutorials explaining how to improve solutions. Sometimes I do not know how to improve my solution, so I need a tutorial for that.

Mostly it is good but sometimes it is very slow. My program, my problem, is a little bigger and my scale is a little larger.

I have not needed to use technical support. I got CPLEX from my teacher and if I have any problems I go to him for help.

I would certainly recommend CPLEX to my colleagues or friends at the university who are doing algorithms. I actually did advise my colleague to use it, because he is also doing the integer program.
