“…Therefore, if a service is part of Skyline, it is expected to offer better parameters than other services [36]. In the above example for SA and SB, the composition of Skyline services is {S5, S2}, in which a set of services are dominated by none of the services in the other composition [11] as {S1, S2}, {S1, S4}, {S2, S2}, {S2, S4}, {S5, S2}, and {S5, S4}.…”

“…Therefore, the proposed model improved harmony search (HS) algorithm and focused on the pitch adjustment rate (PAR) stage. Till date, HS algorithm used fixed values for PAR stages, and many researches modified HS for applications [ 18 , 19 , 40 – 44 ] where PAR is a very important parameter that can help in increasing the variations of the generated solutions by including more solutions in the search space of the optimal solution. This motivated current research in developing our proposed model to a new stage of PAR, called mutation-based HS approach.…”

“…Harmony search (HS) algorithm is an interesting evolutionary algorithm which was developed in an analogy with music improvisation process, to improve the pitches of instruments and obtain better harmony. Whereas HS algorithm is good at identifying high performance of search space, when compared with other evolutionary algorithms [ 17 ], and it has still a drawback: the fixed parameter adjusting pitch adjusting rate (PAR) when applied the web service composition [ 18 ]. Adjusting pitch adjusting rate (PAR) is a very important factor for the high efficiency of the HS algorithm and useful for optimal search [ 19 – 22 ].…”

Web service composition is a method of developing a new web service from an existing one based on business goals. Web services selected for composition should provide accurate operational results and reliable applications. However, most alternative service providers have not yet fulfilled users' needs in terms of services and processes. Service providers, in fact, have focused on enhancing nonfunctional attributes, such as efficiencies of time, cost, and availability, which still face limitations. Furthermore, it remains advantageous to compose services and suitably plan them around business plans. Thus, this study introduces hybrid testing using a combination of the functional and nonfunctional testing approaches. The former was used to design a test case through the equivalence class partitioning technique, and the latter was used to select suitable services for the test results. We find defects and appropriate solutions for combining services based on business requirements. The mutation-based harmony search (MBHS) algorithm is proposed to select web services and to compose with minimum defects. The results of this study reveal that MBHS can support a combination of various services more efficiently and dramatically than other metaheuristic methodologies. Additionally, it helps find appropriate solutions to compose services based on business plans.

Web services are provided as reusable software components in the services-oriented architecture. More complicated composite services can be combined from these components to satisfy the user requirements represented as a workflow with specified Quality of Service (QoS) limitations. The workflow consists of tasks where many services can be considered for each task. Searching for optimal services combination and optimizing the overall QoS limitations is a Non-deterministic Polynomial (NP)-hard problem. This work focuses on the Web Service Composition (WSC) problem and proposes a new service composition algorithm based on the micro-bats behavior while hunting the prey. The proposed algorithm determines the optimal combination of the web services to satisfy the complex user needs. It also addresses the Bat Algorithm (BA) shortcomings, such as the tradeoff among exploration and exploitation searching mechanisms, local optima, and convergence rate. The proposed enhancement includes a developed cooperative and adaptive population initialization mechanism. An elitist mechanism is utilized to address the BA convergence rate. The tradeoff between exploration and exploitation is handled through a neighborhood search mechanism. Several benchmark datasets are selected to evaluate the proposed bat algorithm's performance. The simulation results are estimated using the average fitness value, the standard deviation of the fitness value, and an average of the execution time and compared with four bat-inspired algorithms. It is observed from the simulation results that introduced enhancement obtains significant results.
