#### local p-Median

The formulation for the local p-Median problem covered on Wednesday can be found here. Note that the text does not have this formulation.

#### Quiz 6 date

Quiz 6 will be given on Monday, 10/15.

#### Excel due date

The due date for the excel assignment has been postponed again. You will be notified as to it's exact date by 10/17.

#### Homework 6

The homework which will be used as a basis for the quiz on Friday, 10/12, is to formulate the integer programs that would answer 4.4, 4.5, 4.6, and 4.7. In these problems, only provide the formulation. You do not need to solve them.

#### Wednesday, 10/3

The reading for Wednesday is section 4.2.

#### Homework 5

The reading for Monday is section 4.1. The homework which will be used as a basis for the quiz on Friday is 4.1, 4.2, and 4.17.

#### Some guidance for Test 1

Here are some suggestions for test 1:
• Review the solutions to the quizzes and homework and note the reading the material corresponds to. Be sure you understand how to go back and forth between a general problem and a specific version of the problem.
• Make sure you know how to do the simplex method and understand key definitions such as basic solutions, basis, canonical form, convexity, and extreme points. You should be able to identify when a definition is satisfied or not. You should also know how to convert LPs into canonical form.
• Practice writing formulations. In particular, you should be familiar with the integer constraints from sections 2.9 and 3.1-3.4, such as logical constraints (covering, packing, and partition as well as either-or and if-then constraints), fixed charge, network flow, and the anti-cycling constraints in the MST and TSP problems.
• Make sure you know the definitions related to graph theory that were provided in class such as connected graph, path, cycle, tour, spanning tree, and leaf. You should be able to construct and identify these definitions in a graphical example. Where appropriate, you should also be able to transform graphical examples into their formulation solutions and vice versa.

#### Graph definitions

Here is a document with some definitions and facts about networks. The definitions will be discussed in class on Friday, September 21.

#### Excel due date

The due date for the excel assignment has been postponed to Wednesday, October 10 at 2200.

#### Simplex assignment files, take 2

For some reason, the link to the folder containing the simplex assignment files is not working. Here are the relevent files: FindImprovingDirection_shell.m, UpdateSol_shell.m, FindStepSize_shell.m, PhaseOne.m, USNAplex.m and testprobs.mat.

#### Welcome!!

This is the course page for SA405. Some initial thoughts and information: You can find the tentative schedule for reading and assignments on the linked spreadsheet. CDR Jay Foraker will be teaching the first week for ALL sections as Prof. Phillips is at a conference. The main topic of the week is a review of simplex. Here is the accompanying matlab assignment and the code can be found in this folder.
