problem.setcbcoefevalerror

Purpose

Set a user callback to be called when an evaluation of a coefficient fails during the solve

Synopsis

 problem.setcbcoefevalerror (userfunc, object)
 retval = userfunc (my_prob, my_object, rowindex, colIndex)

Arguments

userfunc	The function to be called when an evaluation fails.
my_prob	The problem passed to the callback function.
my_object	The user-defined object passed as object to setcbcoefevalerror.
RowIndex	The row position of the coefficient.
ColIndex	The column position of the coefficient.
Object	Address of a user-defined object, which can be used for any purpose by the function. object is passed to userfunc as my_object.

Further information

This callback can be used to capture when an evaluation of a coefficient fails. The callback is called only once for each coefficient.
