# Linearize Formulation

 0 Hello, i want to linearize the formulation: min norm(A*x) where A is a matrix, x is a binary vector and norm is the sum over all positive entries of A*x. i doubt it is even a norm. Additional constraints for the x_i: x_1 + x_2 = 1 x_3 + x_4 = 1 .... Thank you asked 23 Oct '14, 10:01 zBirdy 171●2●12 accept rate: 20% 2 Are there any constraints on x? Otherwise x=0 is feasible and gives you an optimal solution. (23 Oct '14, 10:45) Sune yes there are additional constraints. Some of the x_i are 1. If there is no MIP Forumlation maybe as QP or NLP?
