./PIPGcontains the implementaion of PIPG for conic optimization as described in Yu et al. 2022. The two examples in the paper are formulated inex1_problem_data.jlandex2_problem_data.jl. The simulations are carried out in the corresponding notebooksex1_problem_solve.jlandex2_problem_solve.jl.PIPGeq_demo.ipynbimplements an earlier version of PIPG (called PIPGeq) described in Yu et al. 2020./xPIPGcontains the implementation of the extrapolated PIPG for infeasibility detection described in Yu et al. 2022.
Conic optimization solver PIPGeq specialized to affine equality constraint and convex set constraints which allow efficient projections.
