For some types of problems the performance is stable. There are other algorithms, like MetaRisk and generic algorithms, that perform much worse than CPLEX. Though if I were able to get some insights as to what type of problems perform best on CPLEX I would be able to use it more efficiently.

It is pretty stable. It has not crashed this time, though this did happen with the older version when I worked on a large problem.

I haven't had any negative experience with stability.

It is fine.

The stability is good.

I have not faced any issues with instability in CPLEX. My problem-size is not that big. I'm not trying to explain super large problems.

I think it's pretty stable.

It is pretty stable. I have never had any crashes.

From what I've experienced, it doesn't crash that much. There have been a few crashes but compared to the other tools, it is better. 

I have not had any issues with stability.

You need to learn how to play with the settings so it doesn't crash. But if you run on the default settings and your program size is large, it might crash after about an hour.

The stability is okay. For now, I haven't seen it crash. I have seen it become numerically unstable. One of the nice things about CPLEX is that it lets you know that there are certain numerical instabilities. I think that the new feature that they released in the 12.7 version manages to identify that these things are pernicious before trying to solve them, and it recommends other ways to correct that. 

Stability is fine. It's reasonable. Most of the problems are getting slower if I increase the number of nodes or something, but it's a typical thing.

It is stable, though, in one case I noticed that the dual values of the decision variables were not in the correct order. But I managed to find the correct way of presenting that situation and I selected it.

I have not experienced any issues with stability but I have heard from my friends that there are other tools which can perform better than CPLEX sometimes, in terms of computation. 

The stability is reasonably good. Every single version has some bug, which I somehow always encounter. Some of these issues are really severe and literally crash the engine. Very rarely, I find issues which actually impact the accuracy of the results. That has happened twice so far. In general, it is okay.

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.

Great. It never crashed. No lag time.

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.
