The lawsuits contains 30 papers which were chosen and invited from the submissions to the 2nd overseas convention on machine technology, utilized arithmetic and Applications (ICCSAMA 2014) hung on 8-9 may perhaps, 2014 in Budapest, Hungary. The convention is geared up into 7 classes: complex Optimization equipment and Their functions, Queueing versions and function assessment, software program improvement and trying out, Computational tools for cellular and instant Networks, Computational tools for wisdom Engineering, good judgment dependent tools for selection Making and information Mining and Nonlinear platforms and functions, respectively. All chapters within the booklet talk about theoretical and useful concerns hooked up with computational equipment and optimization tools for wisdom engineering. The editors wish that this quantity should be important for graduate and Ph.D. scholars and researchers in desktop technological know-how and utilized arithmetic. it's the wish of the editors that readers of this quantity can locate many inspiring rules and use them to their examine. Many such demanding situations are recommended through specific techniques and versions awarded in person chapters of this book.

Theorem 1. , m are DC functions on C. Suppose further that Assumptions 1-3 are verified. Let δ > 0, β1 > 0 be given. Let {xk } be a sequence generated by DCA1. Then DCA1 either stops, after finitely many iterations, at a KKT point xk for problem (Pgdc )-(12) or generates an infinite sequence {xk } of iterates such that limk→∞ xk+1 − xk = 0 and every limit point x∞ of the sequence {xk } is a KKT point of problem (Pgdc )-(12). Proof. Suppose that at each iterate step xk ∈ Rn , the DC decompositions f0 (x) = g0 (x) − h0 (x); (20) p+ (x) = p1 (x) − p2 (x), (21) satisfy Assumption 1 and 2.

N i,j=1 wij Qij 0 (7) As a conclusion, BMIFP (1) is feasible if and only if QMIFP (2) is feasible, the QMIFP (2) is equivalent to (6), and the formulation (6) is feasible if and only if 0 is the optimal value of the concave minimization problem (7). Therefore, we can solve the problem (7) to determine whether the BMIFP (1) is feasible or not, and if (x, W ) is feasible to (7) such that f (x, W ) ≤ 0, then x must be feasible to QMIFP (2). Concerning on the bounds of the variables (x, W ) in (6), we have that W is bounded if x is bounded due to the definition of W as wij = xi xj .

Later, a Lagrangian dual global optimization algorithm is proposed by the same author in [44]. A sequence of concave minimization problems and DC programs were employed by Liu and Papavassilopoulos [23] on the same problem of Tuan. Mesbahi and Papavassilopoulos [26] have studied the theoretical aspects of the BMI and established equivalent formulations of cone programming. More recently, the generalized Benders decomposition approach has been extended to BMIFP by Floudas, Beran et al. [2, 4]. DCA for BMI/QMI Feasibility Problems 39 In this paper, we will investigate a DC Programming formulation of BMIFP and propose a solution method based on an efficient DC algorithm (DCA).
