# How to explain this? (Mosek\Gurobi\SDPT3)

## (1)For the same model (in CVX) and same data, the cvx feeds solvers with much different constraints, is it abnormal?

Calling Gurobi 5.62: 2051 variables, 2016 equality constraints

Calling Mosek 7.0.0.106: 2051 variables, 35 equality constraints
For improved efficiency, Mosek is solving the dual problem.

Calling SDPT3 4.0: 2051 variables, 35 equality constraints
For improved efficiency, SDPT3 is solving the dual problem.

## (3)Is that means Mosek is a better choice? Or how to explain the results?
