Core API

Detailed Description

methods and headers of the plugin-independent C-API provided by the SCIP header file scip.h.

This module comprises methods provided by the header file scip.h. Including this header into a user-written extension suffices to have all plugin-independent functionality of SCIP available. Plugin-independent user functionality includes the

• creation of problems that SCIP should solve
• fine-grained access to initiate the solving process of SCIP
• access to all sorts of solving process statistics
• commonly used data structures and algorithms
• the management of plugins
• ...

In order facilitate the navigation through the core API of SCIP, it is structured into different modules.
