Range of algorithms for various problems and easy syntax. Review collected by and hosted on G2.com.
Pricing can be improved. For free version, very small problems are allowed to be solved. Review collected by and hosted on G2.com.
We performed detailed and extensive PoC studies with different companies during our vendor selection process. Cplex was the only solver to be able to solve our detailed scheduling problem and IBM was much more professional. In addition to Cplex’s power, we also very much appreciated the support and expertise of IBM l through the implementation of our project. Review collected by and hosted on G2.com.
More help on analyzing infeasible problems and tuning would be nice. Review collected by and hosted on G2.com.
I have been a long-time user of CPLEX. I am particularly a fan of CPLEX studio, which makes writing large-scale models much faster with a dedicated IDE. Additionally, not enough people take advantage of the Constraint programming, which can be faster than solving a MIP with a traditional solver. Review collected by and hosted on G2.com.
I would like to see more of the latest features in CPLEX, like multi-objective, and variable-level control for constraints included in CPLEX Studio Review collected by and hosted on G2.com.
Our business is to build Decision Support solution for our customers. IBM CPLEX (Math Programming and Constraint Programming) enables us to so at minimal risks. From my perspective CPLEX brings two major values for us: (i) best solver in the market, which implies that we can enter into a new engagement knowing that we'll be able to solve the math problem efficiently (ii) ability to freely chose between Math Programming and Constraint Programming. -- We often use a combination of both.

The complexity of the pricing metrics and the fact that the pricing metrics are not always inline with the business value of the solution we build. Review collected by and hosted on G2.com.
The IBM decision optimization has a python API that is easy to implement and integrate with python. Also, it is compatible with basically all the versions of python and it is easy to adapt with anaconda. The creation of decision variables and constraints are easy and it makes the problem easy to formulate. Review collected by and hosted on G2.com.
The software doesn't gives you the ability to modify constraints or the branch and bound technique at low level. Also, the error messages are sometimes inaccurate and can misguide you. Review collected by and hosted on G2.com.
The ease with which I am able to integrate to Matlab and setup my problem formulation. The instructions are clear and the example/sample codes are very helpful. I am impressed with its performance to solve a very large-scale problem with thousands of variables within few minutes. Review collected by and hosted on G2.com.
Nothing specific about the Cplex studio. I haven't explored other capabilities of IBM Decision Optimization, so cannot comment. Review collected by and hosted on G2.com.
High powered solver with useful examples and flexibility to be used in different formats. We use it on the client for model development and then on a server for production. It comes with both Mathematical and Constraint Programming interface and solver. Review collected by and hosted on G2.com.
Data interface is difficult to use so we end up dumping the data to a database or Excel to be able to troubleshoot. Review collected by and hosted on G2.com.
Easy to use with docplex implementation within python environment Review collected by and hosted on G2.com.
Although populate method is a useful tool to get multiple solutions for mixed integer problems, it takes too long to get solutions. It must be improved because It is crucial especially when solution time matters in computational experiments Review collected by and hosted on G2.com.
Because, my primary language is C++. then I can use CPLEX in this software and I haven't seen solver like it which can help me. Review collected by and hosted on G2.com.
There doesn't exist any comprehensive tutorial about all of its function. I just have understood its functions by checking your examples and internter Review collected by and hosted on G2.com.
A product best suited for the business users to define their own rules in a non development environment and take ownership of their business decisions. The ability of the software to readily adapt to the ever changing business needs without much IT involvement is phenomenal. Review collected by and hosted on G2.com.
