eulerian (version 1.0)

eulerian-package: eulerian: A package to handle eulerian paths from graphs

Description

An eulerian path is a path in a graph which visits every edge exactly once. This package provides methods to handle eulerian paths or cycles.

Examples

	require(graph)
	require(eulerian)
	g <- new("graphNEL", nodes=LETTERS[1:4], edgemode="directed")
	g <- addEdge(graph=g, from=LETTERS[1:4], to=LETTERS[c(2:4,1)])
	if(hasEulerianCycle(g)){
		ecycle <- eulerian(g)
		writeLines(paste(ecycle, collapse=" -> "))
	}
