Boundary value problem (BVP) solvers for scientific machine learning (SciML)
Using BigFloat with a TwoPointBVProblem and MIRK4 solver currently fails with the following error: > ArgumentError: matrix type SparseArrays.SparseMatrixCSC{BigFloat,Int64}not supported. Try lu(convert(SparseMatrixCSC{Float64/ComplexF64,Int}, A)) for sparse floating point LU using UMFPACK...
This package takes a massive amount of time to precompile (~100s) and most of that is due to the precompile workload. Removing the precompile workload makes it take 15s (and...
## Features - 17 new Fully Implicit Runge-Kutta (FIRK) solvers: Lobatto IIIa-c 2 to 5 stage versions, and Radau IIa 1,2,3,5,7 - stage versions - Choice of cache with nested...
This pull request changes the compat entry for the `ADTypes` package from `0.2.6` to `0.2.6, 1`. This keeps the compat entries for earlier versions. Note: I have not tested your...
Hi, I am trying to use the `TwoPointBVPProblem` from `BoundaryValueDiffEq`. I put my code in a file and runs it by including in the REPL. The code runs great but...
- [ ] Add more serious workloads - [ ] Add MIRK Methods
Hi, I am trying to solve a two point boundary value problem via continuation but I am encountering an error. I replicate the problem using the example problem. I first...
With the latest changes to nonlinear solve, several algorithms compute VJPs and they don't use $J^T v$ rather they use AD to differentiate the internal nonlinear problem, this causes significant...
This needs to be handled similarly to MIRK, but someone needs to go in and do it.
