... 3. Random Numbers Our next set of algorithms will methods for using a computer to generate random numbers. We will find many uses ... for simulation: to provide random or arbitrary inputs to programs. Also, we will see examples of algorithms which gain efficiency by using random numbers to do sampling or to aid in decision making. Linear

... the classical solution to the network flow problem given below is closely related to the graph algorithms that we have been examining. But this problem is one which is still actively being studied: ... many of the problems that we’ve looked at, the “best” solution has not yet been found and good new algorithms are still being discovered. 433 442 Exercises 1. Give an algorithm to solve the...

Similar implementation techniques are appropriate for other algorithms; with Quicksort we can use them with confidence because ... explicit recursion. This second approach is particularly appropriate for Quicksort and many similar algorithms. We think of the stack as containing “work to be done,” in the form of to be...

... These methods do not just compare keys: they process and compare pieces of keys. Radix sorting algorithms treat the keys as numbers represented in a base-M number system, for different values ... operations needed, and so we’ll be able to write (inefficient) Pascal programs to describe the algorithms that can be easily translated to efficient programs in programming languages that support...
