An unconstrained nonlinear least-square method of optimization of RRRR planar path generators

Optimum synthesis of hybrid-task mechanisms using ant-gradient search method

“…The objective function is minimized under the condition that the generated solution satisfies a set of constraints. Constraints are essential to having a functional mechanism, although they, in general, increase solution complexity [17], and inequality constraints in particular introduce discontinuities [7].…”

Topology optimization of planar linkage systems involving general joint types

“…From this necessity, there have been many research related to mechanism synthesis. The investigations mainly focused on type, number or dimensional syntheses [1][2][3][4][5][6][7][8][9][10][11]. However, there is little effort on the simultaneous number and dimensional syntheses.…”

Mechanism synthesis: a comparison of adaptive and traditional approaches

“…A variety of different numerical techniques can be applied. These include the "traditional" direct search and gradient methods [5,6,7,8], as well as adaptive computing methods such as genetic algorithms [9,10,11,12,13], and methods based around constraint programming [14].…”
