Dear all

I am now using cplex with java to handle a MIP problem
,
and there is a constraint with a maximum expression
:
a[i]=max{a[j],t[i][j]}
,
where a[i] and a[j] are both IloNumVar variables, while t[i][j] is a double variable.

I do not know haw to handle this situation, so I am asking for your heip

Thank you

Did you read the user manual and the reference documentation for Java? It is all there!

cplex.addEq(a[i], cplex.max(a[j], t[i][j]));

Please also look at the various Java examples provided with CPLEX. I am pretty sure example code for all of your questions can be found there.

There are now two duplicate threads (by the same OP), so I suggest nobody respond further to this one.

Please have a look at this post. IBM is generous in allowing their support staff to answer technical questions on this forum, but in my opinion asking them to write your program for you line by line is an abuse of that generosity.
