WebWe can model this as a graph coloring problem: the compiler constructs an interference graph, where vertices are symbolic registers and an edge connects two nodes if they are needed at the same time. If the graph can be colored with k colors then the variables can be stored in k registers. Pattern matching also has applications in graph coloring. WebIntroduction. To study graphs as mathematical structures, we use graph labeling. Graph labeling is a way of assigning labels to vertices, edges, or faces of a graph. It can be done in various ways. Graph coloring is one of the prime methods of labeling. It is a process of assigning labels or "colors" to elements of a graph following certain constraints.
