This trait sets the pattern for optimization algorithms for solving Non-Linear Programming (NLP) problems of the form:
minimize f(x) subject to g(x) <= 0 [ optionally g(x) == 0 ]
where f is the objective function to be minimized g is the constraint function to be satisfied, if any
Classes mixing in this trait must implement a function (fg) that rolls the constraints into the objective functions as penalties for constraint violation, a one-dimensional Line Search (LS) algorithm (lineSearch) and an iterative method (solve) that searches for improved solutions (x-vectors with lower objective function values (f(x)).
