It's not an exaggeration to country that almost all difficulties handled in fiscal idea could be formulated as difficulties in optimization thought. This holds precise for the paradigm of "behavioral" optimization within the pursuit of person self pursuits and societally effective source allocation, in addition to for equilibrium paradigms the place life and balance difficulties in dynamics can frequently be said as "potential" difficulties in optimization.

Example text

Let u be an upper bound of f ∗ . We denote u − d(λ∗ ) as a duality bound between (P) and (D). It is clear that a duality bound is always larger than or equal to the duality gap. If x ∗ solves (L λ∗ ) with λ∗ ≥ 0, and, in addition, the following conditions are satisfied: gi (x ∗ ) ≤ b i , i = 1, 2, . . , m, λi∗ (gi (x ∗ ) − b i ) = 0, i = 1, 2, . . , the duality gap is zero. In this situation, the strong Lagrangian duality condition is said to be satisfied. Unfortunately, the strong Lagrangian duality is rarely present in integer programming, and a nonzero duality gap often exists when the Lagrangian relaxation method is adopted.

I=1 We call α, β an integer box. Let l = (l1 , . . , ln )T and u = (u1 , . . , un )T . Assume that the integer set X in (P) is given by X = l, u . If the objective function is nonincreasing and constraints are nondecreasing, we have the following conclusions: i. If x ∈ l, u is a feasible solution to (P), then for any x˜ ∈ l, x , it holds that f (x˜ ) ≥ f (x). ii. If y ∈ l, u is an infeasible solution to (P), then any point in y, u is infeasible. Therefore, l, x and y, u can be cut from the l, u , without missing any optimal solution of (P) after recording the feasible solution x.

Our outcomes are only slightly worse than those of the special purpose DML method of Shang [17], although we are undertaking to solve the much larger transformed problem and make no use of any specialization. 6 Performance Profiles It is always very difficult to compare different methods based on tables of computational results, unless one method is best on all the tests. We therefore also compare our methods using the ideas given in Dolan and Mor´e [3]. Based on the time used to find the best solution, we can construct a performance profile as follows.
