mosek.ItgSolutionCallback

A handler class for integer solution call backs.

ItgSolutionCallback.callback
void callback (double [] xx)

The integer solution callback is a user-defined function which will be called by MOSEK when it improves the best mixed-integer solution.

The user must not call any MOSEK function directly or indirectly from the callback function.

Parameters:
 xx (double[]) – An array with the values of all variables in the currently best solution. (input)
mosek.DataCallback

A handler class for data call backs.

DataCallback.callback
int callback
  (callbackcode code,
   double [] dinf,
   int [] iinf,
   long [] liinf)

The data callback is a user-defined function which will be called by MOSEK occasionally during the optimization process. In particular, the callback function is called at the beginning of each iteration in the interior-point optimizer. For the simplex optimizers iparam.log_sim_freq controls how frequently the callback is called.

The user must not call any MOSEK function directly or indirectly from the callback function. The only exception is the possibility to retrieve an integer solution, see Progress and data callback.

Parameters:
 
  • code (callbackcode) – Callback code indicating current operation of the solver. (input)
  • dinf (double[]) – Array of double information items. (input)
  • iinf (int[]) – Array of integer information items. (input)
  • liinf (long[]) – Array of long integer information items. (input)
Return:
 

(int) – Non-zero if the optimizer should be stopped; zero otherwise.

mosek.Stream

A stream handler class.

Stream.streamCB
void streamCB (string msg)

The message-stream callback function is a user-defined function which can be linked to any of the MOSEK streams. Doing so, the function is called whenever MOSEK sends a message to the stream.

The user must not call any MOSEK function directly or indirectly from the callback function.

Parameters:
 msg (string) – Text string in the stream. (input)
mosek.Progress

A handler class for progress call backs.

Progress.progressCB
int progressCB (callbackcode code)

The progress callback is a user-defined function which will be called by MOSEK occasionally during the optimization process. In particular, the callback function is called at the beginning of each iteration in the interior-point optimizer. For the simplex optimizers iparam.log_sim_freq controls how frequently the callback is called.

The user must not call any MOSEK function directly or indirectly from the callback function.

Parameters:
 code (callbackcode) – Callback code indicating current operation of the solver. (input)
Return:
  (int) – Non-zero if the optimizer should be stopped; zero otherwise.
