Detailed explanation-1: -In computer science, empirical algorithmics (or experimental algorithmics) is the practice of using empirical methods to study the behavior of algorithms. The practice combines algorithm development and experimentation: algorithms are not just designed, but also implemented and tested in a variety of situations.
Detailed explanation-2: -A Posterior Analysis − This is an empirical analysis of an algorithm. The selected algorithm is implemented using programming language. This is then executed on target computer machine. In this analysis, actual statistics like running time and space required, are collected.
Detailed explanation-3: -The empirical approach can be used when you do not have enough theoretical background on algorithm analysis. It can also be useful when you do not have access to the source code, or your source code is minified. In this case, we can run the algorithm with varying input size.
Detailed explanation-4: -In a scientific context, it is called empirical research. Empirical analysis requires evidence to prove any theory. An empirical approach gathers observable data and sets out a repeatable process to produce verifiable results. Empirical analysis often requires statistical analysis to support a claim.
