This is a repository of solutions to the end-of-chapter exercises in the AMPL book. The book is available for download at the link, along with all the models, data and scripts that comprise the in-chapter examples (but without exercises).
The mathematic programming language involved in this repository is JuMP embedded in Julia that can describe optimization variables, objectives and constraints. The solver SCIP was called by the Julia language to directly solve all of the test instances.
