(Catalyst v14.4.1, JumpProcesses v9.14.2)
I recently updated dependencies for the first time in a while, and I am surprised to find that the solutions for pure jump process problems with all-Int64 initial states now contain Float64 elements.
For example, running the first jump process example in the documentation
using Catalyst
using JumpProcesses
model = @reaction_network begin
kB, S + E --> SE
kD, SE --> S + E
kP, SE --> P + E
end
tspan = (0., 200.)
ps = [:kB => 0.01, :kD => 0.1, :kP => 0.1]
u0_integers = [:S => 50, :E => 10, :SE => 0, :P => 0]
jinput = JumpInputs(model, u0_integers, tspan, ps)
jprob = JumpProblem(jinput)
jump_sol = solve(jprob)
we get:
retcode: Success
Interpolation: Piecewise constant interpolation
t: 200-element Vector{Float64}:
0.0
⋮
200.0
u: 200-element Vector{Vector{Float64}}:
[50.0, 10.0, 0.0, 0.0]
⋮
[1.0, 10.0, 0.0, 49.0]
I am unsure if this is a Catalyst, JumpProcesses or other issue, or if this is even desired behavior now and I need to reconfigure something to change it back. I haven’t really found anything about this change in the documentations, issues or changelogs of Catalyst or JumpProcesses, or on Discourse. What am I missing?
