HELLO !
HELLO !
Hi all
I need to import these equations in my problem
if u(i,j)=0 then x(i,j)=x(i,j-1)+1 & y(i,j)=0
else y(i,j)=y(i,j-1)+1 & x(i,j)=0
which u is a binary variable and x,y are integer.
please help me !
Best regards.

Erwin Kalvelagen to me
This is easily modeled with Cplex indicator constraints, otherwise a
big-M formulation is not too difficult.
