Logo

A JuMP extension for expressing and solving infinite-dimensional optimization problems. Such areas include stochastic programming, dynamic programming, space-time optimization, and more. InfiniteOpt serves as an easy-to-use modeling interface for these advanced problem types that can be used by those with little to no background in these areas. It also it contains a wealth of capabilities making it a powerful and convenient tool for advanced users.

It builds upon JuMP to add support for many complex modeling objects which include:

  • Infinite parameters (e.g., time, space, uncertainty, etc.)
  • Finite parameters (similar to ParameterJuMP)
  • Infinite variables (decision functions) (e.g., y(t, x))
  • Derivatives (e.g., ∂y(t, x)/∂t)
  • Measures (e.g., ∫y(t,x)dt, 𝔼[y(ξ)])

The unifying modeling abstraction behind InfiniteOpt captures a wide spectrum of disciplines which include dynamic, PDE, stochastic, and semi-infinite optimization. Moreover, we facilitate transferring techniques between these to synthesize new optimization paradigms!
