For positive integers m and n, have a m x n matrix A of real numbers. Then also have n x 1 x, 1 x n c, and m x 1 b. Seek x to solve LP1: maximize z = cx subject to Ax = b x >= 0 Instead just as easily can do minimize. Instead of =, mig

Antarctic ozone depletion? A big problem? (1) The ozone molecule is O3 and is unstable so we can have the reaction 2O3 --> 3O2 where ozone returns to just ordinary oxygen. (2) Ozone can be generated by sunlight in the reaction 3O2 --&gt
