I have a following problem:
If I have some function $aX+bY+cZ+mD+nF$ and I want to maximize it and have some constraints, how can I find ALL solutions for this maximum value of the function?
To sum up: I have a function value (e.g. $100$) and I have one optimal solution ($a,b,c,m,n$ - in my case calculated by Excel solver) but I need the rest of the combination of coefficients that results in the function value ($100$).
Can I calculate that somehow?
