	abstract = {Topology Optimization (TO) redistributes the material within a design space to optimize certain objective functions under given constraints. The currently available TO methods do not  consider the designer{\textquoteright}s preferences about the final material layout in the optimized design. Contrarily, an improved design similar to a reference design is required because of the economic, manufacturing, or assembly restrictions. In this article, the proposed heuristic similarity control methods like Energy Scaling Method (ESM), weak passive material method, and an intuitive method of modified design domain are compared with the formal mathematical method of OC-based SIMP with similarity constraint. Initially, the methods are coupled with HCA and OC-based SIMP, for TO of a cantilever beam under static point load. ESM is found to be the most effective and further tested for similarity-based TO with HCA under crash load cases. The results show that ESM can be used to effectively control the TO process.},
