Mutawe, Yahia M. This paper presents a comparative study on the accuracy and A recent study shows that the solutions to the coupler-curve synthesis problems of four-bar linkages can be obtained based on a combination of analytical and graphical methods. Bulatović and Dordević [1] describe the process of opti-mal synthesis of a four-bar linkage using the controlled deviations method of the variables with the diferential evolution algorithm application. In four-bar path generation, the objective is to calculate the linkage dimensions required to achieve or approximate prescribed coupler link path points ( Figure 1).
