Enumeration Type Documentation

enum BCP_message_tag

This enumerative constant describes the message tags different processes of BCP understand.

Enumerator:

BCP_CONFIG_CHANGE	Configurator to TM: machine configuration has changed. TM will unpack the changes from the buffer and then apply them. See the possible changes in the documentation of the configurator in the Config directory.
BCP_CONFIG_ERROR	TM to configurator: error occured while TM tried to implement the changes communicated by the configurator.
BCP_CONFIG_OK	TM to configurator: TM successfully finished implementing the changes communicated by the configurator.
BCP_ARE_YOU_TREEMANAGER	Configurator to all processes: are you the Tree Manager?
BCP_I_AM_TREEMANAGER	TM to configurator: I am the Tree Manager.
BCP_Msg_NoMessage	Used to indicate that there is no message in the buffer of a process. See [BCP_buffer]{BCP_buffer.html}.)
BCP_Msg_AnyMessage	Used when receiving, message with any message tag will be received.
BCP_Msg_User	Used by the user to send a message to the user portion of the other process. Note that the other process will NOT be interrupted to process the message. Message processing will happen when that process decides to check for messages on its own.
BCP_Msg_SomethingDied	Any process to TM: a process has died.
BCP_Msg_UpperBound	Any process to TM or TM to any process: a new upper bound found.
BCP_Msg_FinishedBCP	BCP has finished. The slave process receiving this message will send back statistics to the TM and then terminate. TM will wait for all other processes to terminate.
BCP_Msg_ProcessType	The TM sends the process type to the process (LP, Cut Generator, etc. )
BCP_Msg_ProcessParameters	The TM sends the appropriate parameters to the slave process.
BCP_Msg_CoreDescription	The TM sends the description of the core formulation to the slave process.
BCP_Msg_InitialUserInfo	The TM sends the initial user packed information to the slave process.
BCP_Msg_RootToPrice	Repricing. Does not quite work yet...
BCP_Msg_ActiveNodeData	TM sends the description of a new search tree node.
BCP_Msg_NextPhaseStarts	TM warns an LP process that the second phase will start. (An LP process may use different branching, cut generation and pricing strategies in different phases.)
BCP_Msg_DivingInfo	TM sends diving information.
BCP_Msg_CutIndexSet	Send index set for cuts to be generated in the future.
BCP_Msg_VarIndexSet	Send index set for variables to be generated in the future.
BCP_Msg_NodeDescription_Discarded	The node is discarded (fathomed).
BCP_Msg_NodeDescription_OverUB	The lower bound corresponding to the node is above the upper bound. The node will be saved for the next phase.
BCP_Msg_NodeDescription_Infeas	The node is infeasible. The node will be saved for the next phase.
BCP_Msg_NodeDescription_OverUB_Pruned	The lower bound corresponding to the node is above the upper bound. The node is pruned (will not be saved for the next phase).
BCP_Msg_NodeDescription_Infeas_Pruned	The node is infeasible. The node is pruned (will not be saved for the next phase, compare above).
BCP_Msg_NodeDescriptionWithBranchingInfo	In addition to the node description, branching information is sent as well so that the children of this node can be recreated.
BCP_Msg_PricedRoot	Repricing???
BCP_Msg_FeasibleSolution	The message contains a new MIP feasible solution.
BCP_Msg_LpStatistics	The message contains the statistics the LP process collected.
BCP_Msg_RequestCutIndexSet	Request an index set for cuts to be generated. Empty message body.
BCP_Msg_RequestVarIndexSet	Request an index set for variables to be genarated. Empty message body.
BCP_Msg_ForCG_PrimalNonzeros	Only primal variables currently at nonzero level.
BCP_Msg_ForCG_PrimalFractions	Only primal variables currently at fractional level.
BCP_Msg_ForCG_PrimalFull	All primal variables.
BCP_Msg_ForCG_User	The user packed everything.
BCP_Msg_CutsToCutPool	The message contains cuts for the Cut Pool process.
BCP_Msg_ForVG_DualNonzeros	Pack only dual variables currently at nonzero level.
BCP_Msg_ForVG_DualFull	Pack all dual variables.
BCP_Msg_ForVG_User	The user packed everything.
BCP_Msg_VarsToVarPool	The message contains variables for the Variable Pool process.
BCP_Msg_CutDescription	The message contains the description of a cut.
BCP_Msg_NoMoreCuts	No more (violated) cuts could be found. (Message body is empty.)
BCP_Msg_VarDescription	The message contains the description of a variable.
BCP_Msg_NoMoreVars	No more (improving) variables could be found. (Message body is empty.)
