Detailed Description

functions to create, catch, process, and drop events during the solving process of SCIP

Events can only be caught during the operation on the transformed problem. Events on variables can only be caught for transformed variables. If you want to catch an event for an original variable, you have to get the corresponding transformed variable with a call to SCIPgetTransformedVar() and catch the event on the transformed variable.
