摘要：
This paper presents a global method for approximation and/or construction of curves using constraints. The method is based on a min-max problem which describes approximation and differential geometric characteristics, constrained in order to achieve desired geometrical or physical effects. The numerical solution of the problem takes full advantage of the finite elements method and of constrained optimization algorithms.
