Lagrangian Relaxation
Hi, I am pretty new at Matlab. I am dealing with a problem with has one constraint and I try to solve the problem by using lagrangian relaxation method. However at first I try to get a result for my subproblem. My model is (not in matlab form): Min over i (sum(h(i).s(i))) over i (sum(m(i)/sum(m))* beta(si)) >= b... 11 Apr 2010 12:20
