In the 1970's, Balas introduced the concept of disjunctive programming, which is optimization over unions of polyhedra. One main result of his theory is that, given linear descriptions for each of the polyhedra to be taken in the union, one can easil

Given a combinatorial optimization problem $\Pi$ and an increasing finite sequence $c$ of natural numbers, we obtain a cardinality constrained version $\Pi_c$ of $\Pi$ by permitting only those feasible solutions of $\Pi$ whose cardinalities are membe

Given a directed graph D = (N, A) and a sequence of positive integers 1 <= c_1 < c_2 < ... < c_m <= |N|, we consider those path and cycle polytopes that are defined as the convex hulls of simple paths and cycles of D of cardinality c_p for some p, re

We give a partial description of the (s,t)-p-path polytope of a directed graph D which is the convex hull of the incidence vectors of simple directed (s,t)-paths in D of length p. First, we point out how the (s,t)-p-path polytope is located in the fa

Telle que je l’ai vécue, la récente histoire de Theodor Fontane, de son œuvre en France, est liée à deux projets, un projet européen et un projet franco‑allemand. Le projet européen est un succès. Le projet franco‑ allemand a plutôt é

Considéré par les meilleurs écrivains de ce siècle comme un des pionniers du roman moderne, Theodor Fontane est aussi devenu le plus populaire des classiques allemands du XIXe siècle. Il est urgent de le redécouvrir aussi en France. Considered
