ABSTRACT In the last decade, growing evidence has emerged supporting a non-universal stellar initial mass function (IMF) in massive galaxies, with larger number of dwarf stars respect to Milky Way (bottom-heavy IMF). However, consensus about mechanisms that cause IMF variations is yet be reached. Recently, it been suggested formed early-on cosmic time, via star formation burst, could characteri...

Genetic algorithms (GAs) are powerful heuristic search techniques that used successfully to solve problems for many different applications. Seeding the initial population is considered as first step of GAs. In this work, a new method proposed, seeding called Multi Linear Regression Based Technique (MLRBT). That divides given large scale TSP problem into smaller sub-problems and technique works ...
