Branch-and-bound methods for an MINLP model …
Branch-and-bound methods FOR AN MINLP MODELWITH SEMI-CONTINUOUS VARIABLESERWIN document describes several Branch-and-bound methods tosolve a convex Mixed-Integer Nonlinear Programming ( MINLP ) problem withGAMS. A straightforward MINLP formulation is compared with a piecewiselinear approximation. In addition we include a Branch-and-bound algorithmimplemented following question was posed:Does anybody know an algorithm or mathematical description to solvethe following sum(i=1 to n) c_i +(d_i-c_i)/(1+exp(-(x_i-a_i)/b_i)) (=the sum of n logistic functions), with a_i < 0 and b_i > 0 and c_i < (i=1 to n) x_i <= BudgetWhen x_i >0 then x_i>= Budget_{min}I know that I can describe the last restriction asx_i <= M*y_ix_i >= Budget_{min}*y_iwith y_i binary, but I don t want to use binary would be best to have only linear anybody know another way to solve this problem.
