Lecture 6 Simplex Method: Artifical Starting Solution and ...

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: Convex sets

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 ...

Algebraic Thinking: A Problem Solving Approach

Teaching algebraic thinking using a problem solving approach can be established amid the learning experiences that already exist in most classrooms. It is apparent that this approach evolves and builds upon a child’s ability to consider, see and think about the mathematical concepts within a problem.
