confusion with generalized benders decomposition method

Post by Paulin »

hi, everyone
recently I am using generalized benders decomposition method to solve my model. However, the dual values of the corresponding subproblem equations do not change during every iteration.
moreover, the program converged within two or three iterations, which should be so fast in common sense.
It will be appreciated to receive any suggestions from you.
Thank you.

besides, I found that the variable values of master problem and sub problem do not change during each iteration.
so what might the problem be?
