- I. Ben Gharbia (direction J. Jaffré and J. Ch. Gilbert):
linear and nonlinear complementarity problems  , with application to the simulation of a diphasic flow in a porous medium.
- A. Chiche (direction J. Ch. Gilbert):
decomposition-coordination methods for the middle-term optimization of the electricity production. A warm-up study on the behavior of the augmented Lagrangian on infeasible convex quadratic optimization problems has made good progress  .
- E. Echagüe at IFP (direction J. Ch. Gilbert):
derivative free optimization using SOS (sums of squares) polynomial models ( in progress).
