Hi Andrew, Ok. Let me put this question in a more generic fashion so that its appropriate to this group.
I have a Integer programming formulation which has a variable u{i} where i varies from 1 to n and another variable V. Each u{i} can only take binary values 0 or 1 and same for the variable V. I have a constraint which says u{k} <= u{k+1} for k = 1 to n-1. Which means if a u{i}=1 for certain i=k, then the variable u is 1 for all values of i > k. Now Let k be the least index such that u{k}=1 which means u{i}=1 for i>k i <=n. i want to put a constraint. k <= V. Can I represent it in CPLEX LP format as a linear constraint?
