 ## Description
-`DecisionProgramming.jl` is a [Julia](https://julialang.org/) package for solving multi-stage decision problems under uncertainty, modeled using influence diagrams. Internally, it relies on mathematical optimization. Decision models can be embedded within other optimization models. We designed the package as [JuMP](https://jump.dev/) extension.
