Hello Asma,

var1 / var2 can only be calculated for var2 != 0. So if var2 is binary, var2 = 1 is the only possible solution. Hence var1 / var2 = var1.

Hello everybody,
 
GLPK doesn't accept an constraint in which a variable is devided by an variable, i would like to know if there is some solution to linearize this constraint. knowning that var2 is binary and var 1 is reel in case var1 / var 2.
 
Best regards
Asma
