Hi, I met this problem:

I has construct a model to solve question, the solution prior best Integer is no problem;

but I don't know used what optimization, the best bound and the best integer has problem, and it's violate my constraint. see my attachment.

the "36811.4400" is violate my constraint, I don't know why.

regards

but I don't know how to set this setting in python?

You can take a look at the various examples shipped with CPLEX. They illustrate how to set parameters (and tolerances are just parameters).

very thanks, my model is LP. I'm look the examples, but many parameters setting, I don't know try which parameters, because solve my model need much time,

I want to know the some exact parameters to solve my model, because this parameters have different class, like :method.set(); parameters.optimalitytarget(); or some others;

I have see the cplex c++ have this parameters:

CPX_PARAM_EPRHS (IloCplex::EpRHS) ;

CPX_PARAM_NETEPRHS (IloCplex::NetEpRHS);

CPX_PARAM_BAREPCOMP (IloCplex::BarEpComp) ;

CPX_PARAM_BARQCPEPCOMP (IloCplex::BarQCPEpComp);

CPX_PARAM_EPINT (IloCplex::EpInt)

I don't know the related python parameters names, thanks

regards.

How about taking a look at the documentation? All CPLEX parameters are listed here along with their names in the different APIs.
