Introduction

This document describes the GAMS/SELKIE solver for equilibrium models. This is a research code, so you should set your expectations accordingly. It doesn't come with extensive documentation or a history of continuous development and improvement. To learn more about the algorithms SELKIE implements and related topics, see Y. Kim's Ph.D. thesis or home page.

Usage

To explicitly request that a model be solved with SELKIE, insert the statement

option EMP = selkie;

somewhere before the solve statement in the GAMS source. If SELKIE has been selected as the default EMP solver (e.g. by including EMP=selkie in the command line arguments of the GAMS run) the above statement is not necessary.

SELKIE-specific options can be specified by using a solver option file. While the content of an option file is solver-specific, the details of how to create an option file and instruct the solver to use it are not. This topic is covered in section The Solver Options File.

An example of a valid SELKIE option file is:

* lines starting with a star are comments
diagonalization_method  jacobi
parallel_jacobi         yes
output_group_log        yes
