Messages and codes passed by CBC are listed in the tables below. For a complete list, see COIN/Cbc/CbcMessages.cpp. The notation used is the same as for the printf in the C programming language.
There are several log levels. Setting the log level to be i produces the log messages for level i and all levels less than i.
Table 9.1. CBC Messages Passed At Log Level 0
| Code | Text and notes | ||
|---|---|---|---|
| 3007 | No integer variables - nothing to do | ||
| |||
Table 9.2. CBC Messages Passed At or Above Log Level 1
| Code | Text and notes | ||
|---|---|---|---|
| 1 | Search completed - best objective %g, took %d iterations and %d nodes | ||
| |||
| 3 | Exiting on maximum nodes | ||
| |||
| 4 | Integer solution of %g found after %d iterations and %d nodes | ||
| |||
| 5 | Partial search - best objective %g (best possible %g), took %d iterations and %d nodes | ||
| |||
| 6 | The LP relaxation is infeasible or too expensive | ||
| |||
| 9 | Objective coefficients multiple of %g | ||
| |||
| 10 | After %d nodes, %d on tree, %g best solution, best possible %g | ||
| |||
| 11 | Exiting as integer gap of %g less than %g or %g%% | ||
| |||
| 12 | Integer solution of %g found by heuristic after %d iterations and %d nodes | ||
| |||
| 13 | At root node, %d cuts changed objective from %g to %g in %d passes | ||
| |||
| 14 | Cut generator %d (%s) - %d row cuts (%d active), %d column cuts %? in %g seconds - new frequency is %d | ||
| |||
| 16 | Integer solution of %g found by strong branching after %d iterations and %d nodes | ||
| |||
| 17 | %d solved, %d variables fixed, %d tightened | ||
| |||
| 18 | After tightenVubs, %d variables fixed, %d tightened | ||
| |||
| 19 | Exiting on maximum solutions | ||
| |||
| 20 | Exiting on maximum time | ||
| |||
| 23 | Cutoff set to %g - equivalent to best solution of %g | ||
| |||
| 24 | Integer solution of %g found by subtree after %d iterations and %d nodes | ||
| |||
| 26 | Setting priorities for objects %d to %d inclusive (out of %d) | ||
| |||
| 3008 | Strong branching is fixing too many variables, too expensively! | ||
