event_solvingstats.c File Reference

Detailed Description

eventhdlr for writing various types of information during the solving process

Author

Gerald Gamrath

If the filename is specified, a file is created and the eventhandler is installed to catch all events announcing that a node was solved or that a new best solution was found. Whenever one of these things happens, a line is printed to the file with the following information: 1) solving time 2) number of processed nodes (including the current node) 3) number of open nodes 4) number of LP iterations 5) number of variables in the master problem 6) current global dual bound 7) current primal bound
