Algorithms in Computer Systems

Basic definition of algorithm in mathematics is step by step procedure to solve a problem. Algorithms are basic and most important area in a writing an error free programs. Fig. 1 illustrates flow chart of a computer algorithm. One of the most essential thing to remember is that there can be various algorithms for the same problem but some algorithms are much better than others. Technically, algorithm and programs are actually not the same thing, they differ at the level of precision. It is often expressed loosely defined format called “pseudo code” which matches programming language closely leaving out specific details that can be added later. Pseudo code doesn’t have hard and fast rules about commands, but it is halfway between an information instruction and specific program. Although, there are plenty of algorithms that are already there and are yet to be implemented, designed with various methods, techniques and composition of various methods. This editorial paper gives brief insights about few from plethora of various algorithms in computer systems; for instance, algorithms that can predict growth of cities, algorithms that can create three dimensional shapes, algorithms for customization of video game difficulty using big data, algorithms in the smart watch, and finally, algorithms to detect fake users on social networks
