Shortest paths in graphs with negative edge weights
Let G = (V, E ) be a directed graph with edge weights cuv for each edge (u, v ) E . Let |V | = n and |E | = m. Cost c(p) of a path p = (v0 , v1 , . . . , vk ) is
k i=1 cvi1 ,vi .
Shortest path from s t
Optimal substructure property. Characterizing the solution. Recurrence. Bottom up computation.
Let X = x1 , x2 , . . . , xm and Y alphabet . = y1 , y2 , . . . , yn be two sequences of characters from a nite
The idea that a process can be random is not a modern one; we can trace the notion far back into the history of human thought and certainly see its reections in gambling and the insurance business, each of which reach into
We began our study of algorithmic techniques with greedy algorithms, which in some sense form the most natural approach to algorithm design. Faced with a new computational problem, weve seen that its not hard to propose multi
Chapter 5 Divide and Conquer
Divide-and-conquer refers to a class of algorithmic techniques in which one breaks the input into several parts, solves the problem in each part recursively, and then combines the solutions to these sub-problems into an overal
Introduction: Some Representative Problems
1.1 A First Problem: Stable Matching
As an opening topic, we look at an algorithmic problem that nicely illustrates many of the themes we will be emphasizing. It is motivated by some very natural and pr
All Pairs Shortest Paths
Let G = (V, E ) be a directed graph with edge weights cuv for each edge (u, v ) E . Let V = cfw_1, 2, , n and |E | = m. Cost c(p) of a path p = (v0 , v1 , . . . , vk ) is
