Re: [Help-glpk] Set pair e.g. ( (i, j) in T) not properly implemented in matrix generation (i.e. CPLEX LP formulation, etc.) in particular data set (e.g. repeating i's in (i, j) in T

Noli,

Your model is quite complicated, so it's difficult to me to inspect it. 
As I understand you suspect that some constraints are not generated for

subject to Adjacent_Constraint{ t in PERIOD, (i1,i2) in ADJACENT, j in
AGECLASS: isHarvestable[t,i1,j] and isHarvestable[t,i2,j] and (i1,i2) in
ADJACENT }: Y[t,i1,j] + Y[t,i2,j] <= 1;

while they should be. Please find t, i1, i2, and j, for which this
happens, and add a display statement before s.t. Adjacent_Constraint ...
to display t, i1, i2, j, PERIOD, ADJACENT, AGECLASS, and isHarvestable.
Thanks.
