CALLBACKCHECKTIMEDELAY

Description
Minimum delay in milliseconds between two consecutive executions of the CHECKTIME callback in the same solution process
Type
Integer
Topic area
Callback
Values
0 
Callback delay is disabled - the callback is executed every time;
n>0 
Callback invocation is suppressed if less than n milliseconds have passed since the last invocation.
Default value
0
Note

The CHECKTIME callback may be invoked very often and can lead to an overhead. This control enables users to specify a minimum delay between two consecutive calls, such that the overhead becomes controllable. Note that system time is used to measure the time between two consecutive calls. Therefore, a positive delay value may result in a nondeterministic sequence of callback invocations. Note that the counter is reset at every invocation of a solution process via XPRSlpoptimize, XPRSmipoptimize, etc.
