epecinstances's Introduction

EPECsolve

This repository is part of the EPECSolve project, and contains the data and instances of the paper When Nash Meets Stackelberg (to appear, Management Science).

Code
Instances
arXiv pre-print with the detailed mathematical description of our instances

Goverments act as Stackelberg leaders by trading energy, with the aim of minimizing their emissions, and eventually to maximize tax incomes. Within each country, energy producers act as Stackelberg followers and play a Nash game between themselves, aiming to maximize their profits. A full description of these instances is available here

Folder organization

We generated three instances sets for our computations.

InstanceSetA contains 149 instances where there are 3 to 5 countries
InstanceSetB contains 50 instances with strictly 7 countries. These instances were selected if the full enumeration algorithm was not able to solve them within 10 second on a single core machine.
InstanceSetInsights contains 50 instances with 2 countries with 3 followers each. Such instances are useful to derive managerial insights from our model
ChileArgentina contains the ChileArgentina case-study data and instance generator
ResultParser.py produces the tables that can be found in the arXiv pre-print (and the paper)
PaperTables.xlxs contains the aggregate results of our tests and the content of the tables reported in our paper.
