Bounds for the Solutions of Cubic Diophantine Equations
Howard Kleiman
The original version of this paper did not take into account that there may be solutions (x_0, y_o)in Z X Z of f(x,y) = x^3 + p(y)x + q(y) = 0 even though w_0 = (-3D(y_0))^(1/2) is…

The Floyd-WarshallAlgorithm and the Asymmetric TSP
Howard Kleiman
We improve proofs in "The Floyd-Warshall Algorithm, the AP and the TSP (III). We also simplify the method for obtaining a good upper bound for an optimal solution.
