Chapter 8 Primal-Dual Method and Local Ratio
... 1. If a zero-cost solution can be found, return one. 2. Otherwise, find a suitable decomposition of w into two weight functions w1 and w2 = w − w1, and solve the problem recursively, using w2 as the weight function in the recursive call. ...

Observations on the Quintic Equation with five unknowns
... concerns with the problem of determining non-trivial integral solutions of the nonhomogeneous Quintic equation with five unknowns given by x4-y4=37(z2-w2)p3. A few relations between the solutions and the special numbers are presented. ...

... Some students observed that this could be interpreted as “4/3 of A MORE than 1/3 of A,” in other words, 5/3 of A. In this case, A+30 = 5 A / 3, giving A=45. This was judged a reasonable interpretation of the problem and so both answers were allowed. One former mathlete wrote: The issue is whether "4 ...
