This constrained optimization problem is solved by using the Sequential Least-Squares Quadratic Programming (SLSQP), where a nonlinear constrained optimization is replaced by a standard
quadratic program with a quadratic approximation of the Lagrange function and linear approximation of the constraints [4].
To enable fast and efficient computation, we formulate the optimization problem as a
quadratic program. We also examine how the inclusion of cash management bills would affect costs, using a heuristic approach based on shadow prices derived from the quadratic programming solution.

After the transformation, the original problem was transformed into an equivalent convex
quadratic program problem:
Recently, many modern heuristics stochastic search algorithms such as genetic algorithm (GA) [6], evolutionary programming (EP) [7], tabu search (TS) [8], particle swam optimization (PSO) [9, 10], differential evolution algorithm (DE) [11-21], biogeography-based optimization (BBO) [22], chaotic self-adaptive differential harmony search algorithm (CSADHS) [23], quadratically constrained
quadratic program method (QCQP) [24], Krill herd algorithm (KHA) [25], and harmony search with new pitch (NPAHS) [26] have shown great potentials in solving the nonlinear ELD or DED problems.
Solving a linear program is much easier and faster than solving a
quadratic program. The optimal portfolio consists of at most 2T + 2 assets regardless of the size, n while Markowitz model may consist of n assets.
The previous optimization problem is a convex
quadratic program which can be solved by using the well-known Lagrange multiplier method.
Therefore, the problem can be formulated as an integer
quadratic program in n [multiplied by] m assignment variables.
For an iterative point [x.sup.k], a new
quadratic program (QP) subproblem is given by
Recently, a new but important linear conic tool called completely positive programming (CPP) has been used to study the nonconvex
quadratic program with linear and binary constraints.
[33] formulated the GAP as a mixed binary
quadratic program with minimizing the slack time overall variance as the objective function; an assumption has been stated such that the flights are sequenced with the smallest arrival time.
