For the priority table algorithms everything gets placed into the first bin when the table is first initialized. Might be good to distribute the reactions across bins when initializing to...

This would allow MTK to specify boundary constraints that look like `[x(t) < 3]`, where we want every value of the solution to be less than 3. Thinking the codegen...

I have this problem that MIRK3, MIRK4, and MIRK6 seem to handle fine, but MIRK5 ends up having very large errors on: ```julia using BoundaryValueDiffEq, BenchmarkTools function lotkavolterra!(du, u, p,...

With codegen to BVProblem being added to MTK soon it'd be nice if the BVP solvers could work with the Jacobian, W matrix, etc. that can be generated from it....

bug

see things like https://link.springer.com/article/10.1007/s10589-011-9454-7. Not knowledgeable here so if anybody knows of additional solver methods that'd be appreciated.

The JuMPDynamicOptProblem uses InfiniteOpt's default interpolation (linear or orthogonal collocation) for definite-time constraints/costs which may be different from the collocation polynomial used in the actual solve. Probably should make these...

Fix #3513, requires https://github.com/SciML/SciMLBase.jl/pull/978

@AayushSabharwal this is the one we discussed: **Describe the bug 🐞** When an observable is updated in a symbolic callback as in the example below (y depends on g, g...
