Varranges

Given an inverse input list, generates the minimal and maximal values of
 the variables (linear combinations of unknowns).

utilities

optimize

Functions that read and solve linear inverse problems (food web problems, linear programming problems).
These problems find solutions to linear or quadratic functions:
min or max (f(x)), where f(x) = ||Ax-b||^2 or f(x) = sum(ai*xi)
subject to equality constraints Ex=f and inequality constraints Gx>=h.
