We present a novel direct integral pseudospectral (PS) method (a direct IPS method) for solving a class of continuous-time infinite-horizon optimal control problems (IHOCs). The method transforms the IHOCs into finite-horizon optimal control problems in their integral forms by means of certain parametric mappings. which are then approximated by finite-dimensional nonlinear programming... https://www.parisnaturalfoodes.shop/product-category/extra-gentle-shampoo-unscented/
