Optimization.jl is heavily integrated with the ModelingToolkit.jl symbolic system for symbolic-numeric optimizations. It provides a front-end for automating the construction, parallelization, and optimization of code. Optimizers can better interface with the extra symbolic information provided by the system.
There are two ways that the user interacts with ModelingToolkit.jl. One can use
AutoModelingToolkit for automatically transforming numerical codes into symbolic codes. See the OptimizationFunction documentation for more details.
Secondly, one can generate
OptimizationProblems for use in Optimization.jl from purely a symbolic front-end. This is the form users will encounter when using ModelingToolkit.jl directly, and its also the form supplied by domain-specific languages. For more information, see the OptimizationSystem documentation.
