FICO Xpress Optimization Examples Repository

Solving an MPS problem using a REST webservice, from NodeJS

Description

In this example, the Xpress Executor should first be configured to solve MPS problems. Then, you run the coco-mps-xe.js program locally; this uses REST webservice requests to send the coco.mps.gz file to the Xpress Executor and remotely solve the problem, then download and display the results. This example does not require a local installation of Xpress.
