chrono::ChSolverVI Class Reference
Description
Base class for solvers aimed at solving complementarity problems arising from QP optimization problems.
The problem is described by a variational inequality VI(Z*x-d,K):
| M -Cq'|*|q|- | f|= |0| | Cq -E | |l| |-b| |c|
with l \(\in\) Y, C \(\in\) Ny, normal cone to Y
Also Z symmetric by flipping sign of l_i:
|M Cq'|*| q|-| f|=|0| |Cq E | |-l| |-b| |c|
- case linear problem: all Y_i = R, Ny=0, ex. all bilaterals
- case LCP: all Y_i = R+: c>=0, l>=0, l*c=0
- case CCP: Y_i are friction cones
For details on the supported types of solvers see ChIterativeSolverVI and the concrete iterative VI solvers.
