This work explores constrained optimization techniques with various basic objective functions to move nodal points around, and to improve the quality of unstructured grids. The negative volumes can be avoided with appropriate volume constraints. The objective function of distance and aspect ratio type combined with volume constraints are useful equilateral smoothers. The objective function of volume type combined with Delaunay triangulation can change the connectivity rapidly and equalize the volume distribution. The constrained optimization technique combined with a grid generation procedure can become a useful tool for obtaining a user-desired grid.
