Слайд 2


Process optimization code Optimization - a transformation in which the result of the system remains unchanged, but improve some of its characteristics. The most common goals of optimization when developing the code: reduce the execution time of programs, improve performance, compactification of code, memory consumption, minimizing energy consumption, reducing the number of input / output.

Common Sub-Expression Elimination (CSE) (Устранение общих подвыражений) This optimization is the following: if you use the calculation of any expression two or more times, it can be calculated once and then to substitute all uses of its expression.

Слайд 5


Performing arithmetic operations on variables of different types Comparison of execution time of commands s = a*0.5 and s = a/2 The aim of the study was to determine which of the basic arithmetic operations on variables of different types are faster. Also need to find out how the performance of an operation depends on the type of the operands.
