Replace box constraints with Ellipsoid robust constraint
Hi I am attempting a robust optimisation problem using the knapsack example 1.2.1 in the robust doc as a template. I calculate the possible % deviation for each variable in the model (P23PERCENT). I...

Xpress range constraint
Using the latest Xpress interface I can add a constraint x_i + y_i <= UB_i for all i like this: xprsProb.addConstraints(nrNodes, i -> sum(x+y).leq(UB)); How can I add a range constraint like: LB_i...1 year agoPlace FICO® Xpress Optimization ForumFICO® Xpress Optimization Forum1 unread comment1 unread0Views0likes1CommentLazy constraints on LP problems
Dear all, I have an LP problem (no integer constraints) where a large number of constraints can in most cases be avoided in most cases just as for Lazy Constraints. However, lazy constraints seem ...3 years agoPlace FICO® Xpress Optimization ForumFICO® Xpress Optimization Forum1 unread comment1 unread0Views0likes1CommentI have an optimization model where setting certain variables can lead to constraint violations. Is there a way to identify and remove all infeasible constraints before solving the model?
