Generate Galaxy-Like Word Cloud Using Molecular Cloud Evolution

The evolution of molecular cloud(MC) brings about various stars and galaxies. A simple two-stage MC based evolutionary model is proposed to reorganize a word cloud into a galaxy-like cloud. Based on the model, an evolutionary algorithm simulates the moving and colliding of stage-1 MCs, and the merging and collapsing of stage-2 MCs. In addition, it considers long range force based disturbance, which often starts the formation of stars. Our experiment suggests that it produces galaxy-like word clouds for users to choose from.
