SCIP_NodeType中值的含义

Question

Is there a combination of parameter settings so that the search tree only contains "simple" node types, ie not SCIP_NODETYPE_{PROBINGNODE, DEADEND, JUNCTION, PSEUDOFORK, FORK, SUBROOT, REFOCUSNODE} ? Even if it means disabling some functionality.

I'm also not really sure about what the different node types really mean, so any pointers to documentation would also be very useful.

Answer 1

The meaning of the different node types is explained here . If you have a closer look, you will understand that those types reflect the internal organization of the tree. They necessarily occur during tree search and cannot be skipped via parameters.

If you insist: setting limits/nodes = 1 will process only the root node of SCIP, and the tree will only consist of a focus node and its 2 children.
