[Coin-discuss] cbc message level

[John J Forrest]

Matt,

Will fix - problem will be because osiCbc is both a solver and a branch 
and bound code.  But at present message handling is a mess and after some 
input from Michael Bussieck I am probably going to move a type into each 
set of messages i.e. branchandbound, solver, coin, cgl etc and enable you 
to set levels more elegantly just ta the top level.

Fixed - problem was really that OsiCbc uses a default strategy of printing 
which overrode yours.

You just need  getModelPtr one.

John

[Coin-discuss] cbc message level






Hi,


Through OsiCbc, how do I make Cbc completely quiet?

  OsiCbcSolverInterface * si = new OsiCbcSolverInterface();

  si->messageHandler()->setLogLevel(0);
  si->getModelPtr()->messageHandler()->setLogLevel(0);
  si->getRealSolverPtr()->messageHandler()->setLogLevel(0);


I tried all of those, but am still getting these messages:

Cbc0009I Objective coefficients multiple of 1
Cbc0013I At root node, 0 cuts changed objective from 2.25 to 3 in 2 passes
Cbc0014I Cut generator 0 (Probing) - 0 row cuts (0 active), 1 column 
cuts  in 0.001 seconds - new frequency is -100
Cbc0014I Cut generator 1 (Gomory) - 2 row cuts (0 active), 0 column 
cuts  in 0 seconds - new frequency is -100
Cbc0014I Cut generator 2 (Knapsack) - 0 row cuts (0 active), 0 column

0 column cuts  in 0.001 seconds - new frequency is -100
Cbc0004I Integer solution of 3 found after 2 iterations and 0 nodes
Cbc0001I Search completed - best objective 3, took 2 iterations and 0 
nodes
Cbc0004I Integer solution of 3 found after 2 iterations and 0 nodes


Thanks,
Matt
