Estimate cost of an optimal diapath, Data Structure & Algorithms

Assignment Help:

Normally a potential y satisfies yr = 0 and 0 ³ yw - cvw -yv. Given an integer K³0, define a K-potential to be an array y that satisfies yr = 0 and K ³ yw - cvw -yv. Show that for a K-potential y we have that for each node v, yv is within Kn of being the cost of an optimal r-v dipath, i.e. show c(P) + Kn ³ yv for any r to v dipath P in G. HINT: Generalize our proposition from class that said that for a normal potential y, c(P)³yv for any r to v dipath P in G.
