## How to obtain random decimal numbers...

Maple

Is there a simple command to generate decimal numbers in a given range?

For example, I wish to obtain a randomly generated number between, say ... -0.5 and 0.5.

Maple

Given a basic list of data, is it possible to extract the distribution type /  equation / probability density function?

Maple , Maple Toolboxes

I was looking to see if anyone has come across a Maple routine for a savings algorithm - specifically, Clarke and Wright. In fact, any classical savings heuristic would also be interesting.

Any guidance would be truly appreciated.

## How to extract specific values from solu...

Maple , MaplePrimes

If binary constraints are imposed on an optimization problem and LPSolve presents a solution, is it possible to extract the variables that have zero or one assigned to them? This would be most useful if there are many variables, for example...

If a solution is returned that looks like ...

[x[001]=0, x[101]=1, x[201]=0, x[301]=1, ....], how can I filter those solutions that equal zero?

## How to extract specific decision variabl...

Maple

I was curious to know if one can extract a specific solution from a LPSolve routine.

As an example, consider the following output to a constrained linear problem. The objective value is 8 and the decision variable values (binary) are given.

Sol := [8, [w[1, 1] = 1., x[0, 0, 1] = 0, x[0, 1, 1] = 1, x[0, 2, 1] = 0, x[1, 0, 1] = 0, x[1, 1, 1] = 0, x[1, 2, 1] = 1, x[2, 0, 1] = 0, x[2, 1, 1] = 0, x[2, 2, 1] = 0, y[0, 0] = 0., y[0, 1] = 0., y[1, 1] = 2.]]

I am interested to know if we can isolate any variable value from this solution. I know that Sol[1] will return 8, and Sol[2] will return the remaining terms. But what if I wanted, say, x[1,2,1] alone?
