This report concerns a method for computing a substitute inverse for linear programs with a staircase structure. The constraints of a staircase structure linear program are of the following form: A(1)x(1)=d(1); B(t-1)x(t-1)+A(t)x(t) = d(t); (t = 2 ..., T). Letting m(i) be the number of constraints in period i, the substitute inverse consists of the inverse of T matrices which are m(i) x m(i), i = 1 ..., T as opposed to the actual inverse which is m x m, m = Sum over i m(i). Hence the substitute inverse would require significantly less storage than the actual inverse. Two methods are presented for updating the substitute inverse, both of which consist of updating some, but not necessarily all of the T smaller inverses. The first, a pivoting method, requires appending one or more columns to the smaller inverse and pivoting on the appended columns. The second requires adding one to T dyad matrices to the smaller inverses. Computational efficiency of both methods can be tested to a large degree using standard linear programming codes. (Author).

Written by current and former surgical oncology fellows of the world-renowned M.D. Anderson Cancer Center, this portable handbook is a practical guide to established surgical oncology principles for each organ system. This new Fourth Edition features extensive updates including new chapters on reconstructive surgery in the cancer patient. Concise chapters illustrated with algorithms and line drawings outline the essential elements of diagnosis, staging, and clinical management of solid tumors treated in surgical practice. The authors emphasize multidisciplinary treatment planning, including therapy sequencing and biologic therapies.
