Using notions from complementary pivot theory, it is shown that if each fixed point of f lies interior to some piece of linearity, then f has an odd number of fixed points. In addition, an algorithm is given for computing a fixed point of f."@en . "Operations Research." . . "Linear programming." . . "Theorems." . . . . "Simplex method." . .
