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 ...

Lecture 2 : Convergence of a Sequence, Monotone sequences

Lecture 2 : Convergence of a Sequence, Monotone sequences In less formal terms, a sequence is a set with an order in the sense that there is a rst element, second element and so on. In other words for each positive integer 1,2,3, ..., we associate an element in this set. In the sequel, we will consider only sequences of real numbers.

Therefore, uniform convergence implies pointwise convergence. But the con-verse is false as we can see from the following counter-example. Example 10 Let {fn} be the sequence of functions on (0, ∞) defined by fn(x) = nx 1+n2x2. This sequence converges pointwise to zero. Indeed, (1 + n2x2) ∼ n2x2 as n gets larger and larger. So, lim n→∞ ...
