Optimizing problem R
Hi, I have a problem with R optimization. I try to copy excel solver acts to R. Solver has some problems with nonlinear optimisation. Suppose we have resources: (X,Y,Z)=(20, 30, 25) and services: matrix(10,11,0, 13,12,10, 0,24,26), nrow=3. Now we should optimize the problem: max( min(a/10,b/11) + min(aa/13,bb/12,cc/10) + min(24/bb,26/cc) ) so that a+aa<=15 b+bb+bb<=35 cc+ccc<=40 Can
