Opis:: We present a new approach to the concrete planning (CP) - a stage of theWeb service composition in the PlanICS framework. A new hybrid algorithm (HSA) based on a combination of Simulated Annealing (SA) with Satisfiability Modulo Theories (SMT) has been designed and implemented. The main idea of our hybrid solution is to use an SMT-based procedure in order to generate an initial individual and then improve it during subsequent iterations of SA. The experimental results show that HSA is superior to the other methods we have applied to the CP problem, including Genetic Algorithm, an SMT-based approach, and our previously developed hybrids.

Tytuł:: Solving the abstract planning problem using genetic algorithms
Autorzy:: Skaruz, J.

Powiązania:: https://bibliotekanauki.pl/articles/93024.pdf

Tematy:: abstract planning

web service composition
Opis:: The paper presents a new approach based on genetic algorithms to the abstract planning problem, which is the first stage of the web service composition problem. An abstract plan is defined as an equivalence class of sequences of service types that satisfy a user query. Intuitively, two sequences are equivalent if they are composed of the same service types, but not necessarily occurring in the same order. The objective of our genetic algorithm (GA) is to return representatives of abstract plans without generating all the equivalent sequences. The paper presents experimental results compared with the results obtained from SMT-solver, which show that GA finds solutions for very large sets of service types in a reasonable time.

Wydawca:: Polska Akademia Nauk. Instytut Badań Systemowych PAN
Tematy:: automated composition
web services
abstract planning
Opis:: The paper proposes a method to cover the world of web services with a uniform semantics, possibly simple but enabling to arrange complex flows of service invocations. The flows are built according to fully declarative user's intentions, specified in a language common for the descriptions of services and for the query. In the approach we model the world of services and of the subjects they operate on using a uniform knowledge database and an objectoriented manner. The current work describes the first phase of the composition: making an abstract plan, i.e., giving an answer how (with what types of services) the required effect can be obtained. The problem of creating a plan is converted to building a specialized graph.
