x is continuous variable, ix, i1,i2 and i3 are binary variables. Constant is a constant
x <= [1- (i1+i2+i3)]*Constant
Question 1: Does Formulation 1 and Formulation 2 have performance difference (solving time)? Formulation 2 created extra binary variable but remove the coefficient on the other binaries.
Question 2: My model contains 100k those constraint and binary variable per constraint can go up to 48. Do you think this type of constraint would cause slow solving?
