	)

creates a concurrent solver type and includes it in SCIP.

Returns

SCIP_OKAY is returned if everything worked. otherwise a suitable error code is passed. see SCIP_RETCODE for a complete list of error codes.

Precondition

This method can be called if scip is in one of the following stages:

• SCIP_STAGE_INIT
• SCIP_STAGE_PROBLEM

Parameters

scip	SCIP data structure
name	name of concurrent_solver
prefpriodefault	the default preferred priority of this concurrent solver type
data	the concurent solver type's data
