The quadratic assignment problem (QAP) is one of the fundamental combinatorial optimization problems in the branch of optimization or operations research in mathematics, from the category of the facilities location problems.

How long would it take each machine to stuff a batch of envelopes by themselves? Let (t) be the amount of time it takes the first machine (machine a) to stuff a batch of envelopes by itself. That means that we can use the pythagorean theorem to say, left( 25t right)2 left( 20left( t - 2 right) right)2 left( 300 right)2 this is a quadratic equation, but it is going to need some fairly heavy simplification before we can solve it so lets do that. Now, we know that the distance traveled by an object (or car since thats what were dealing with here) is its speed times time traveled.

Also, as we will see, we will need to get decimal answer to these and so as a general rule here we will round all answers to 4 decimal places. Again, the negative doesnt make any sense and so machine a will work for 3. What are the dimensions of the field? So, well let (x) be the length of the field and so we know that (x 3) will be the width of the field.

This object represents a strategy for determining which direction a should be carried out along. This implementation uses a basic armijo backtracking search with polynomial interpolation. Since the second car, lets call that car b, starts out two hours later then we know that it will travel for (t - 2) hours.

This particular object is an implementation of the polak-ribiere conjugate gradient method for determining this direction. In the sketch we will assume that the two cars have traveled long enough so that they are 300 miles apart. B frac1t 1 note that its okay that the work rates contain (t).

Now, we also know that area of a rectangle is length times width and so we know that, now, at this point, weve got to deal with the fact that there are two solutions here and we only want a single answer. So, we have a right triangle here. A 25t mboxdistance of car b 20left( t - 2 right)endarray at this point a quick sketch of the situation is probably in order so we can see just what is going on.

Now, from a physical standpoint we can see that we should expect to not get complex solutions to these problems. One car starts out driving north at 25 mph. Job left( mboxwork rate of machine a right) times left( t right)hspace0. We will give the results of the quadratic formula, we just wont be showing the work. Instead, you should try the arguments.

So, lets convert to decimals and see what the solutions actually are. So, we have one positive and one negative. Two cars start out at the same point. Also, as we will see, we will need to get decimal answer to these and so as a general rule here we will round all answers to 4 decimal places. It is generally very effective but if your problem has a very large number of variables then it isnt appropriate.

In this section were going to go back and revisit some of the applications that we saw in the section and see some examples that will require us to solve a quadratic equation to get the answer. From the stand point of needing the dimensions of a field the negative solution doesnt make any sense so we will ignore it. Working together they can stuff a batch of envelopes in 2 hours. However, it is generally not as good as the l-bfgs algorithm (see the this is a function that takes another function, f(x), as input and returns a new function object, g(x), such that where xlower and xupper are vectors of box constraints which are applied to x. Again, unlike the first example, note that the time for machine b was not the second solution from the quadratic without the minus sign.

This particular object is an implementation of the bfgs quasi-newton method for determining this direction. It does this by automatically expanding the matrix elements and invoking the function. This is a function that takes another function as input and returns a function object that numerically computes the derivative of the input function. Therefore, the length of the field is 7. For an example showing how to use the non-linear least squares routines look performs a line search on a given function and returns the input that makes the function significantly smaller. Now, we also know that area of a rectangle is length times width and so we know that, now, at this point, weve got to deal with the fact that there are two solutions here and we only want a single answer. That means that we can use the pythagorean theorem to say, left( 25t right)2 left( 20left( t - 2 right) right)2 left( 300 right)2 this is a quadratic equation, but it is going to need some fairly heavy simplification before we can solve it so lets do that. Also, we are going to assume that you can do the quadratic formula work and so we wont be showing that work. B frac1t 1 note that its okay that the work rates contain (t). This method uses an amount of memory that is linear in the number of variables to be optimized.

We also know that we want the width of the field to be 3 feet longer than the length of the field. The width is 3 feet longer than this and so is 10. This method uses an amount of memory that is linear in the number of variables to be optimized. What are the dimensions of the field? So, well let (x) be the length of the field and so we know that (x 3) will be the width of the field. So we have the following distances traveled for each car.

So, it looks like the car a traveled for 10. Y) ridgelambdalengthsquared(w) such that sum(abs(w)). This method uses an amount of memory that is quadratic in the number of variables to be optimized.

For example, suppose you had a function like this matrix args 3,4,5callfunctionandexpandargs(f, args) calls f(3,4,5) since it allows a wide range of input functions to be given to the optimizer, including functions with explicitly named arguments like x,y,z as shown above. Now, we also know that area of a rectangle is length times width and so we know that, now, at this point, weve got to deal with the fact that there are two solutions here and we only want a single answer. Again, the negative doesnt make any sense and so machine a will work for 3. Now, from a physical standpoint we can see that we should expect to not get complex solutions to these problems.

This particular object is an implementation of the polak-ribiere conjugate gradient method for determining this direction. As with the previous example the negative answer just doesnt make any sense. An office has two envelope stuffing machines. Now, the coefficients here are quite large, but that is just something that will happen fairly often with these problems so dont worry about that. Notice as well that this is not the second solution without the negative this time, unlike the first example.

Now, we know that the distance traveled by an object (or car since thats what were dealing with here) is its speed times time traveled. This implementation uses a basic armijo backtracking search with polynomial interpolation Buy Quadratic Assignment Online at a discount

It is generally very effective but if your problem has a very large number of variables then it isnt appropriate. Also, even though the problem didnt ask for it, the second car will have traveled for 8. So, lets convert to decimals and see what the solutions actually are. That means that it will take the second machine (machine b) (t 1) hours to stuff a batch of envelopes by itself. So, it looks like the car a traveled for 10.

Do not expect this to always happen. Therefore, the length of the field is 7. An introduction to the general purpose non-linear optimizers in this section can be found.
