# Solve The Optimization Problem

Cut Generation: Applied 1 mir cut, and 2 strong CG cuts. To correct these issues, try to scale the coefficient matrices, eliminate redundant linear constraints, or give tighter bounds on the variables.

For example, in Example \(\Page Index\), we are interested in maximizing the area of a rectangular garden.

Certainly, if we keep making the side lengths of the garden larger, the area will continue to become larger.

Compare the number of steps to solve an integer programming problem both with and without an initial feasible point. Intlinprog stopped because the objective value is within a gap tolerance of the optimal value, options. The intcon variables are integer within tolerance, options. Therefore, the problem variables have an implied matrix form.

The problem has eight integer variables and four linear equality constraints, and all variables are restricted to be positive. The uses to solve linear least-squares problems, see Least-Squares (Model Fitting) Algorithms.

Given \(100\) ft of wire fencing, determine the dimensions that would create a garden of maximum area. Solution Let \(x\) denote the length of the side of the garden perpendicular to the rock wall and \(y\) denote the length of the side parallel to the rock wall.

Then the area of the garden is \(A=x⋅y.\) We want to find the maximum possible area subject to the constraint that the total fencing is \(100\, ft.\) From Figure \(\Page Index\), the total amount of fencing used will be \(2x y.\) Therefore, the constraint equation is \(2x y=100.\) Solving this equation for \(y\), we have \(y=100−2x.\) Thus, we can write the area as \(A(x)=x⋅(100−2x)=100x−2x^2.\) Before trying to maximize the area function \(A(x)=100x−2x^2,\) we need to determine the domain under consideration..pass_color_to_child_links a.u-inline.u-margin-left--xs.u-margin-right--sm.u-padding-left--xs.u-padding-right--xs.u-relative.u-absolute.u-absolute--center.u-width--100.u-flex-inline.u-flex-align-self--center.u-flex-justify--between.u-serif-font-main--regular.js-wf-loaded .u-serif-font-main--regular.amp-page .u-serif-font-main--regular.u-border-radius--ellipse.u-hover-bg--black-transparent.web_page .u-hover-bg--black-transparent:hover. Content Header .feed_item_answer_user.js-wf-loaded . However, what if we have some restriction on how much fencing we can use for the perimeter?In this case, we cannot make the garden as large as we like.For example, companies often want to minimize production costs or maximize revenue.In manufacturing, it is often desirable to minimize the amount of material used to package a product with a certain volume. These usually arise from linear constraint matrices that have large condition number, or problems that have large solution components.

To correct these issues, try to scale the coefficient matrices, eliminate redundant linear constraints, or give tighter bounds on the variables.
