Lecture 6 Artificial Start: Two-phase method • Sometimes, it is not easy to find an initial feasible solution (i.e., to choose initial bases yielding a feasible point) • Two-phase method is used in such situations • In first phase, a feasibility problem associated with the LP is solved by a simplex method • In the second phase, the solution from the first phase is used to start

Lecture 2 Open Set and Interior Let X ⊆ Rn be a nonempty set Def. The set X is open if for every x ∈ X there is an open ball B(x,r) that entirely lies in the set X, i.e., for each x ∈ X there is r > 0 s.th. for all z with kz − xk < r, we have z ∈ X Def. A vector x0 is an interior point of the set X, if there is a ball B(x0,r) contained entirely in the set X Def. The interior of the ...

Algorithmique et Structures de Données

Un algorithme est une suite de raisonnements ou d'opérations qui fournit la solution d'un problème. Le programme ne sera que la traduction de l'algorithme dans un langage de programmation, c'est-à-dire, un langage plus simple que le français dans sa syntaxe, sans ambiguïtés, que la machine peut utiliser et transformer pour exécuter les ...
