Use the numbers found in an optimization problem somewhere else?

Hello all,
Let’s say we solve maximization problem and create a table for a specific range. An example:

c1 = Table[NMaximize[{(x*y - y^2 + x - x^2)*a/2, 0 <= y <= x <= 1, a*(1 - y) <=  1}, {x, y}], {a, 1, 6, 0.1}]

Now resulting table have elements in a form such:

{0.166667, {x -> 0.666667, y -> 0.333333}

In order to solve another problem, I need to use these x and y values. How can I call them in a different place?

Best, Ovunc

p.s. I took the table to Excel, created three rows. I imported the Excel file into Mathematica, but this time I cannot convert it to the matrix form I am interested in.

Ovunc,

you can reference the x and y variables with a replace.

Let’s say you want the x value from the fifth result – so take the second element from the fifth result (which is the list of x and y rules):

x /. c1[[5, 2]]

You can use this to restructure your results into a matrix:

lookupTable = Map[{#[[1]], x /. #[[2]], y /. #[[2]]} &, c1];

and look at it as a grid:

Grid[lookupTable , Frame -> All]

or export / use it.

Amazing! Thank you so much!
