Stellar Initial Mass Function (IMF) is an important aspect for delineating a clear picture of star formation scenario in a broad spectrum of environments - from star clusters, associations, field stars to much bigger ones like dwarf galaxies, giant galaxies, cluster of galaxies etc. Whether the stellar initial mass function is universal or sensitive to environment is of crucial importance. The present study deals with the simulation of stellar IMF using Markov Chain Monte Carlo Simulation in young star clusters under various theoretical considerations and compared with the existing observations available so far to check for universality and mass seggregation if any.

Keywords: Initial mass function; Markov chain; Monte Carlo; Star cluster
