These constraints can benefit significantly from constraint! if n is large.
Consider reformulating this as
c = ExaModels.constraint(
core,
- z[1] for b1 in 2:dom.ELEMS+1;
lcon=-Inf,
ucon=0.0,
)
ExaModels.constraint!(
core,
b1 -1 => integral[b1+1, e1] for b1 in 2:dom.ELEMS+1
)
* solved error in pde_models * solved constraint error in pde_models * fixed summation problem in pde_models * added semicolonn to scopf * remove local test in pde_models.jl * add catmix draft * added chain,methanol,minsurft and fixed catmix and pde_models * added polygon, tetra, torison and triangle * reduce variables integral in pde_models * changed channel.jl from JuMP to ExaModels * finished glider.jl * merged conflicts in pde_models * solved constraint error in pde_models * solved error in pde_models * added chain,methanol,minsurf,catmix,polygon,tetra,torison,triangle and fixed pde_models * reduce variables integral in pde_models * changed channel.jl from JuMP to ExaModels * finished glider.jl * merged conflicts in pde_models * solved constraint error in pde_models * add rectangular coordinates in opf.jl * removing division in constraints * removing division in constraints * removing division in constraints * solved merge issue * fixed bounds for voltage * fixed bounds in opf.jl * Update bounds for voltage in opf.jl The original constraint was not correct because it should be the square of magnitude. * included more problems for testing * add parameters into model to avoid testing errors * solving input error in tetra_model * fixed input error in pde_models * fixed input for runtests.jl * fixed name of the problem torsion.jl * Delete src/torison.jl Delete wrong name model * Changing function names in ExaModelsExamples.jl Torsion has replaced torsion * added test cases to runtest.jl * added LuksanVleckModels in the package * changed incorrect package name and make it more accessible * modified formulation in tetra.jl

This PR adds the
dirichlet,henonandlane_emdeninstances from the COPS benchmark. These PDE-constrained instances are the most challenging ones, and pause difficulties to the automatic differentiation.Unfortunately, the compilation time is currently too long in ExaModels, and I was not able to solve these three instances despite trying different workarounds.
My observations with other AD backends are:
