Oct 25, 2022 · I don't know about dummy demand but it seems to me you can simplify the problem to have fewer variables. I think of constraints as being inequalities like items 1-5 whereas equations ('equalities') like 6-7 allow us to just remove variables from the calc and thus simplify it.

Jan 29, 2012 · Homework Statement The shaded area on graph represents the feasible region of a linear programmin problem whose objective function is to be maximized. Label each of the following statements as True or False, and then justify your answer based on the graphical method. In each case, give an...

Apr 4, 2010 · Simplex Method --- Programming Problem Homework Statement Here's the question - Conside the linear programming problem: maximise P = -3x + y, subject to 3x + 2y =< 24, 4x + 9y =< 36,-2x + y =< 1, and x >= 0, y >= 0. Represent the problem as an initial Simplex tableau and use the Simplex algorithm to solve the problem.

Jul 22, 2019 · It works well on this sized problem and it teaches the point that integer programming is more complicated than it first appears. But this approach is quickly overwhelmed by surprisingly small problems. If the goal is to learn integer programming techniques, the "brute-force" approach misses the point.

Feb 14, 2011 · Because you have a sum of several linear functions defined on a segment, the result is a piecewise linear function. Depending on the sign of the slope, the linear functions attain their minima on the left (for negative slope) or right (for positive slope) side of the segment.

Nov 25, 2012 · I'm reading a book about linear programming and network flows. In chapter 2 when it talks about convex sets and their analysis it talks about extreme points and extreme directions of a convex set. I understand the definitions of extreme points and extreme directions, but I don't know how I should find them.

Jul 25, 2022 · Linear Programming "Possibility Restaurant" Homework Statement Angela Fox and Zooey Caulfield were food and nutrition majors at State University, as well as close friends and roommates. Upon graduation Angela and Zooey decided to open a French restaurant in Draperton, the small town where the university was located.

Jan 4, 2011 · Operations research is concerned with all kinds of discrete optimization problems. Having a basic knowledge in this field is generally a useful skill to have if you will be developing software for quantitative purposes (say, calculating models, data analysis, etc). You'd be surprised at how often network optimization and routing problems occur.

Oct 30, 2013 · Most physics problems involve solving systems of differential equations, both ordinary and partial, and in many cases, non-linear. Python is often used to support programs written in Fortran or C++. Then there are packages like Matlab, Mathematica, Maple, . . . .

Aug 13, 2016 · Eventually though your lack of programming skills will become a drag on your research teammates, and physics students are a resentful sort of bunch to those who don't pull their fair share of work for the group. Study both, take one or two courses in a programming language of your choice.
