Problem 1. An undirected graph G has width w if the vertices can be arranged in a se- quence V1,2,3,…,Vn such that each vertex v; is joined by an edge to at most w preceding vertices. (Vertex vj precedes if i.) Use induction to prove that every graph with width at most w is (w+1)-colorable

Systems Engineering and Lean Thinking Systems Engineering grew out of the space industry in response to the need to deliver technically complex systems that worked flawlessly upon first use SE has emphasized technical performance and risk management of complex systems

Structure Editor Window o open the structure Editor window o click the structure Editor the main tool bar se the Tools I Structure Editor item structure by choosing the File I Open I Structure menu item and structure Editor will start automatically Only one Structure Editor window can be opened at any one time in the program. If you click the structure Editor button, or you choose the Too/s I Structure Editor menu, and the Structure Editor is already opened, this window becomes active
