problem.setcbcoefevalerror

Purpose

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

Synopsis

 problem.setcbcoefevalerror(callback, data)
 retval = callback(my_prob, my_object, rowindex, colindex)

Arguments

callback	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 data to setcbcoefevalerror.
rowindex	The row position of the coefficient.
colindex	The column position of the coefficient.
data	Address of a user-defined object, which can be used for any purpose by the function. data is passed to callback 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.
