Final solution of a nonlinear non-convex problem solved with Knitro (via Xpress) looks worse than the initial solution
Dear all, I have a couple of questions on the use of the procedure setinitval and more in general on the use of an initial solution for solving a nonlinear problem. I am solving a series of nonline...
Hi Caterina,
unfortunately there is currently no convenient way to load in an slx solution as initial values, although we might consider adding this in the future.
At the moment you would need to store the solution values in an array and then set the initial values from there, for example:
itersol: array(integer) of real
(solve iteration i)
forall (i in I) itersol(i) := getsol(x(i))
(transfer itersol to the other model)
forall (i in I) setinitval(x(i), itersol(i))
Best,
Tristan
