Multiple-gradient descent algorithm (MGDA) for multiobjective optimization. (English. Abridged French version) Zbl 1241.65057
Summary: One considers the context of the concurrent optimization of several criteria $$J_{i}(Y) (i=1,\ldots ,n)$$, supposed to be smooth functions of the design vector $$Y\in \mathbb R^{N} (n\leqslant N)$$. An original constructive solution is given to the problem of identifying a descent direction common to all criteria when the current design-point $$Y^{0}$$ is not Pareto-optimal. This leads us to generalize the classical steepest-descent method to the multiobjective context by utilizing this direction for the descent. The algorithm is then proved to converge to a Pareto-stationary design-point.
