synopsis:            Solve Lagrange multiplier problems
description:
 Numerically solve convex Lagrange multiplier problems with conjugate gradient descent.
 .
 For some background on the method of Lagrange multipliers checkout the wikipedia page
 <http://en.wikipedia.org/wiki/Lagrange_multiplier>
 .
 Here is an example from the Wikipedia page on Lagrange multipliers
 Maximize f(x, y) = x + y, subject to the constraint x^2 + y^2 = 1
 .
 @
   \> maximize 0.00001 (\\[x, y] -> x + y) [(\\[x, y] -> x^2 + y^2) \<=\> 1] 2
   Right ([0.707,0.707], [-0.707])
 @
 .
 For more information look here: <http://en.wikipedia.org/wiki/Lagrange_multiplier#Example_1>
 .
 For example, to find the maximum entropy with the constraint that the probabilities sum
 to one.
 .
 @
   \> maximize 0.00001 (negate . sum . map (\\x -> x * log x)) [sum \<=\> 1] 3
   Right ([0.33, 0.33, 0.33], [-0.09])
 @
 .
 The first elements of the result pair are the arguments for the
 objective function at the maximum. The second elements are the Lagrange multipliers.
