The lagrangian package

[Tags:bsd3, library, test]

Numerically solve convex lagrange multiplier problems with conjugate gradient descent.

For example, find the maximum entropy with the constraint that the probabilities sum to one.

> solve 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 minimum. The second elements are the lagrange multipliers.
