	push start to stack
	set all start edges weight to 0

	while stack size is > 0 AND currentvertex weight < steps
		currentvertex equals pop stack

		for v all vertexes connected to currentvertex

				push v to stack
				v weight equals currentvertex+1
				set v as discovered

		set currentvertex as fully discovered
