Dual values of MIP
回答済みHi, We are investigating dual variables from MIP problems by first solving an original MIP problem, then fixing the solution of the integer variables and solving a corresponding linear program. We ...

Retriving dual values from relaxed MIP
回答済みHi, I have defined a MIP model that solves a unit-commitment problem. I have first tried the fixed()-method to retrieve the dual values. Now, I want to do the same through relaxing the binary mode...

Sensitivity analysis, quadratic constraints
回答済みI have a model that initially contained SOS constraints and quadratic constraints, on which I want to conduct a sensitivity analysis. First I used the fixed method to fix the SOS and then I tried t...

Retrive attribute Pi
ユーザーの入力を待っています。I have a pure linear model, but I cannot retrieve the dual value (Pi). Are there any common reasons why this might happen? See my code below, for it only tries to retrieve the dual values in the ca...
