Use container / cgroup cores when automatically picking threads

Currently, when auto selecting the number of threads, it looks like cplex uses the number of cpu cores. That doesn't work for containers that are cpu limited using cgroups, as the number of threads will be equal to the host machine's cpu core coun...

Produce log during OPL Extract phase similar to Solve Engine Log

Many OPL real-world optimisations spend a large proportion of the overall solve time performing extraction/generation and there is no log of what is happening during this time. There should be a log produced during Extract similar to the Engine Lo...

a new parameter to control to force MIPStart if the variables are feasible

CPLEX choose to use MIPStart or not accoring to the heuristic. But sometimes the user think MIPStart values as particular variables is the best way to solve the problem. So we’d like to request a new parameter to control to force MIPStart if the v...

CPLEX object create by oplrun and concert shall be equal

the CPLEX object created by an OPL model is not the same as tyhe CPLEX object created with concert technology.It creates limitation and complexity that prevent people to use OPL in many cases, such advance algorithms with call backs manual cuts......

Cplex.solveFixed() for OPL Script

Is there an equivalent of Cplex.SolveFixed() for OPL Script ? I'm looking for dual costs of a MILP. So I'd like to 1) solve it to get the solution. 2) solve the corresponding LP with fixed integer variables 3) get dual costs I don't know in advanc...
