... Many of the algorithms appropriate for such search problems are closely related to the search algorithms that we studied in Chapters 14-17. The parallels will be quite evident. Few geometric algorithms ... running time of geometric algorithms. As usual in such situations, we do have empirical evidence which suggests good algorithms for particular applications. Also, many of the alg...

... book. Analysis of Algorithms In this short chapter we’ve already seen three different algorithms for the same problem; for most problems there are many different available algorithms. How is ... need to be studied in order to understand the algorithms. Simple algorithms can give rise to complicated data structures and, conversely, complicated algorithms can use simple data structu...

... software capabilities certainly can have a significant impact on specific algorithms, but good algorithms on old machines are, for the most part, good algorithms on new machines. One reason for this is that the ... merits further study. The many variants on algorithms for the union-find problem of Chapter are ably categorized and compared by van Leeuwen and The algorithms for shorte...
