This work tackles the open pit planning problem in an optimal control framework. We study optimality conditions for so-called continuous formulation using Pontryagin’s Maximum Principle, and introduce a new, semi-continuous that can handle optimization of two-dimensional mine profile. Numerical simulations are provided several test cases, including global one-dimensional final pit, first result...

Controlling rigid body dynamic simulations can pose a difficult challenge when constraints exist on the bodies’ goal states and the sequence of intermediate states in the resulting animation. Manually adjusting individual rigid body control actions (forces and torques) can become a very labour-intensive and non-trivial task, especially if the domain includes a large number of bodies or if it re...
