Analysis parameterized algorithms on the bases of elasticity to functions complexity

We give a brief overview of results and problems of parameterized algorithmics as the new direction of computational complexity theory. We offer a new indicator of computational complexity for parameterized algorithm which can be used to measure rate a growth of function complexity from many variables. This indicator is a private elasticity of the function complexity. We offer a two-dimensional classification parameterized algorithms to multiplicative forms a presentation of the functions complexity. We give a mathematical basis to analysis a level impact of parameter for time execution of parameterized algorithm.
