Re: Solver

[Vinicius Provenzano <viniciusxp yahoo com br>]

Well, thank you for the clicking in a cell stuff... Let's see if I can
explain what I meant by the bin costrint...

Sometimes I can use a bin variable to make a cell be or 0 or 1, to make
a decision...

If I don't have the bin costraint, I have to set up 3 costraints:
Xij>=0; Xij<=1; Xij==> int...
