(a) Prof. Luo proposes the following greedy algorithm for obtaining an approximate solution to this maximization problem: $ \begin{aligned} & \text { Initialize } S \leftarrow{}, T=0 \ & \textbf { for } i=1,2, \ldots, N \text { do } \ & \quad \textbf { if } T+a_i \l...
A critical issue in modeling the WTA problem is the time performance of the developed algorithms, subject only recently contemplated in related publications. This paper presents a hybrid approach which combines an ant colony optimization with a greedy algorithm, called the Greedy Ant Colony System (...

its construction method,the greedy algorithm was designed.Finally,an example was analyzed to demonstrate the application of this algorithm.The results proved that a gate assignment method based on the flight connecting tree could effectively simplify complexity of the model,and improved solving efficiency...
The problem is NP-hard even in the case N=3 and a branch and bound algorithm is the only known algorithm for guaranteeing an optimal solution [21]. Thus, the general approach to obtaining good solutions is based on heuristics and considerable preprocessing. While there are a wide array of ...

Several exact and heuristic algorithms have been proposed to solve the Weapon-Target Assignment problem for several years. Some of them are described briefly below: 3.5.1 Maximum marginal return (MMR) algorithm Maximum marginal return algorithms are algorithms that assign weapons sequentially with each...
