AMPL: Summation over variable ranges
Hi,I have a constraint in an IP model as follows:\sum_{t = t_i}^{t_i'} a_{j,t} = t_{i'} - t_ia_{j,t} is a binary variable, and t_i & t_{i'} are variables that aredefined by other constraints. Now, is it possible in AMPL to express asummation in the way shown above? From the user&#...

Integer solution for minimum cost flow problems
Hi,In a general minimum cost flow problem, I would get an integer solutionif the arc capacities and demands are integer. But if I enforce anintegral lower bound on the arc flow (such as 1 <= X_ij <= 1; what Ireally wanted to do is to fix flow on an arc), is my solution stillguranteed to be...
