Rod Cutting Using Dynamic Programming Part 2
Serling Enterprises buys long steel rods and cuts them into shorter rods, which it then sells. Each cut is free. The management of Serling Enterprises wants to know the best way to cut up the rods.
Rod Cutting Using Dynamic Programming Part 1
We will now discuss how to convert CUT-ROD into an efficient algorithm, using dynamic programming.
The dynamic-programming method works as follows. Having observed that a naive recursive solution ( we discussed in part 1) is inefficient because it solves the same subproblems repeatedly, we arrange for each subproblem to be solved only once, saving its solution. If we need to refer to this subproblem’s solution again later, we can just look it up, rather than recompute it.
We introduce Chomsky Normal Form, which is used to answer questions about context-free languages.
Chomsky Normal Form. A grammar where every production is either of the form A → BC or A → c (where A, B, C are arbitrary variables and c an arbitrary symbol). Example:
S → AS | a
A → SA | b

A useful form for dealing with context free grammars is the Chomksy normal form. This is a particular form of writing a CFG which is useful for understanding CFGs and for proving things about them. It also makes the parse
