Abstract
The article compares two ways of solving the arithmetic operations sign placement problem: method based on recursion and dynamic programming based one which uses the memoization. Limitations on the intermediate results of the problem solution are identified and justified. It is shown that the use of memoization to cut off ineffective search options makes it possible to accelerate the corresponding algorithms execution by tens times.
Highlights
As it's known, programming memoization is the storing code snippets to prevent recalculations [9]
Memoization is used when memorizing the results of a function for the given parameters values
In this article we show how memoization can be used to speed up arithmetic signs placement problem
Summary
As it's known, programming memoization is the storing code snippets to prevent recalculations [9].
