This paper deals with the local problem of optimizing several analytic functions at the same time. We prove that the Milnor number of an isolated complete intersection singularity at a local Pareto optimal point is odd. Furthermore, high-order necessary and almost sufficient conditions are given, allowing one to recognize from the Newton diagram of an analytic mapping at the origin whether this point is a local Pareto optimum.
