I am trying to solve an optimization problem with CVX. I can solve it in my pc with a correct answer. But when I move the same matlab files onto a linux server with the same matlab and CVX versions as my pc, it can’t solve it and says that the status is infeasible. And I found that the number of constraints are different on two machines: 55 on my pc and 161 on Linux. Also, there is a line “For improved efficiency, SeDuMi is solving the dual problem” when I solve the problem on my pc but not on Linux.

on my pc:

Calling SeDuMi 1.21: 216 variables, 55 equality constraints

For improved efficiency, SeDuMi is solving the dual problem.

SeDuMi 1.21 by AdvOL, 2005-2008 and Jos F. Sturm, 1998-2003.

Alg = 2: xz-corrector, Adaptive Step-Differentiation, theta = 0.250, beta = 0.500

Split 6 free variables

eqs m = 55, order n = 33, dim = 413, blocks = 2

nnz(A) = 165 + 0, nnz(ADA) = 3025, nnz(L) = 1540

on Linux:

Calling SeDuMi 1.32: 210 variables, 161 equality constraints

SeDuMi 1.32 by AdvOL, 2005-2008 and Jos F. Sturm, 1998-2003.

Alg = 2: xz-corrector, Adaptive Step-Differentiation, theta = 0.250, beta = 0.500

eqs m = 161, order n = 21, dim = 401, blocks = 2

nnz(A) = 244 + 0, nnz(ADA) = 25921, nnz(L) = 13041
