Homotopy method
The homotopy method is a method for fixed-point computation, based on the mathematical concept of homotopy. The method was devised in 1972 by B. Curtis Eaves.[1] Given a function f, for which we want to find a fixed point, the algorithm works by starting with an affine function that approximates f, and deforming it towards f while following the fixed point. ApplicationsThe homotopy method has been used for market equilibrium computation.[2] Further readingThe method is further explained in a book by Michael Todd,[3] which surveys various algorithms developed until 1976.
