Li Wang, Yongzhong Song, ON THE OPTIMIZATION OF EXTRAPOLATION METHODS FOR SINGULAR LINEAR SYSTEMS, Journal of Computational Mathematics, Vol. 26, No. 2 (March 2008), pp. 227-239 ...

We give a branch-and-cut algorithm for solving linear programs (LPs) with continuous separable piecewise-linear cost functions (PLFs). Models for PLFs use continuous variables in special-ordered sets ...
