We develop two kinds of cutting planes for signomial programming: outer approximation cuts and intersection cuts. The cuts and experiments are described in the paper Cutting planes for signomial programming.

The cutting planes are generated in each node of the branch and bound algorithm, and we use SCIP to implement them. Note that the codes are developed in a Linux environment. Before running the code, please build them using an appropriate environment. The outer approximation cuts are integrated in a new version of SCIP9.

The benchmark contains selected instances from MINLPLib (which have signomial terms). There is a bash file to run the experiments.
