Entropy Studies of Software Market Evolution
نویسنده
چکیده
Entropy is a concept commonly used in various disciplines. In thermodynamics, it is used to measure the randomness of particles (atoms, molecules, etc.). In information theory, it is used to measure the amount of information in a program unit (variable, expression, function call, etc.) In this paper, entropy is used to measure the diversity of a marketplace. The formulas used in thermodynamics and information theory to calculate entropy is adapted for market analysis. Based on the theory and observations of thermodynamics, we hypothesize that the diversity/entropy of certain market tends to increase over time. The case studies of the evolution of programming languages, operating systems, web browsers, and web servers verify the hypothesis.

Considering distribution characteristics of natural cracks in coal-rock, and based on da...
متن کاملStudying Software Evolution Using Clone Detection
In modern software engineering, researchers regard a software system as an organic life form that must continue to evolve to remain successful. Unfortunately, little is known about how successful software systems have evolved, and consequently little has been learned from previous experience. In this paper, we demonstrate a heuristic to reconstruct evolution processes of existing software syste...

Abstract. The concept of entropy has been widely extended to other fields, including information theory and economic research. The economic financial sector of any country is the supplier of financial resources and real economic activities, which are divided into two parts: the money market and the capital market. In this paper, two criteria, approximate entropy and standard deviation have been...
