In 1983, Hopcroft and Krishnamoorthy defined a new type of graph colouring called harmonious colouring. Harmonious colouring is a proper vertex colouring such that no two edges share the same colour pair. The least number of colours needed to harmoniously colour a graph is called the harmonious chromatic number. We will examine the results found for the(More)
We develop a simple and efficient adaptive mesh generator for time-dependent partial differential equations with singular solutions in two dimensional spaces. The mesh generator is based on minimizing the sum of two diagonal lengths in each cell. We also add second order difference terms to obtain smoother and more orthogonal mesh. The method is(More)
