WebbSimplicial Continuation, or Piecewise Linear Continuation (Allgower and Georg) is based on three basic results. The first is If F (x) maps IR^n into IR^ (n-1), there is a unique linear interpolant on an (n-1)-dimensional simplex which agrees with the function values at the vertices of the simplex. The second result is: Webb1 feb. 1992 · The new algorithm, which is referred to as disaggregate simplicial decomposition (DSD), is given along with a specialized solution method for the disaggregate master problem.
