* autodiff: add ConstantHessian structure Allow to avoid computing Hessian-vector products with AutoDiff if the Hessian is constant. (e.g. for voltage_magnitude_constraints) * Remove hard-coded parts in computation of objective's gradient. * Add a new function cost_production, with associated kernels. * Specify ramping constraints with penalties in objective * Compute gradient and Hessian of ProxAL's objective with AutoDiff.
* ReducedSpaceEvaluator now uses batch Hessian by default * add support for batch Hessian * add batch_jacobian function * generate Hessian code with metaprogramming * change signature of hessian_lagrangian_penalty_prod!
* Allow to deport the computation on the GPU, while using a CPU compatible solver. * add CUSOLVERRF in the dependencies * fix transpose in kernels
