CommonSolve.jl: The Common Solve Definition and Interface

This holds the common solve, init, and solve! commands. By using the same definition, solver libraries from other completely different ecosystems can extend the functions and thus not clash with SciML if both ecosystems export the solve command. The rules are that you must dispatch on one of your own types. That's it. No pirates.

General recommendation

solve function has the default definition

solve(args...; kwargs...) = solve!(init(args...; kwargs...))

So, we recommend defining

init(::ProblemType, args...; kwargs...) :: SolverType
solve!(::SolverType) :: SolutionType

where ProblemType, SolverType, and SolutionType are the types defined in your package.

To avoid method ambiguity, the first argument of solve, solve!, and init must be dispatched on the type defined in your package. For example, do not define a method such as

init(::AbstractVector, ::AlgorithmType)

API

CommonSolve.initFunction
iter = CommonSolve.init(args...; kwargs...)

Solves an equation or other mathematical problem using the algorithm specified in the arguments. Generally, the interface is:

iter = CommonSolve.init(prob::ProblemType,alg::SolverType; kwargs...)::IterType
CommonSolve.solve!(iter)::SolutionType

where the keyword arguments are uniform across all choices of algorithms. The iter type will be different for the different problem types.

Missing docstring.

Missing docstring for solve. Check Documenter's build log for details.

CommonSolve.solve!Function
CommonSolve.solve!(iter)

Solves an equation or other mathematical problem using the algorithm specified in the arguments. Generally, the interface is:

iter = CommonSolve.init(prob::ProblemType,alg::SolverType; kwargs...)::IterType
CommonSolve.solve!(iter)::SolutionType

where the keyword arguments are uniform across all choices of algorithms. The iter type will be different for the different problem types.
