This paper introduces a new human-based metaheuristic algorithm called Sewing Training-Based Optimization (STBO), which has applications in handling optimization tasks. The fundamental inspiration of STBO is teaching the process of sewing to beginner tailors. The theory of the proposed STBO approach is described and then mathematically modeled in three phases: (i) training, (ii) imitation of the instructor’s skills, and (iii) practice. STBO performance is evaluated on fifty-two benchmark functions consisting of unimodal, high-dimensional multimodal, fixed-dimensional multimodal, and the CEC 2017 test suite. The optimization results show that STBO, with its high power of exploration and exploitation, has provided suitable solutions for benchmark functions. The performance of STBO is compared with eleven well-known metaheuristic algorithms. The simulation results show that STBO, with its high ability to balance exploration and exploitation, has provided far more competitive performance in solving benchmark functions than competitor algorithms. Finally, the implementation of STBO in solving four engineering design problems demonstrates the capability of the proposed STBO in dealing with real-world applications.
This paper introduces a new human-based metaheuristic algorithm called Sewing Training-Based Optimization (STBO). The fundamental inspiration of STBO is the process of teaching sewing to beginner tailors. The process is described in three phases: (i) training, (ii) imitation of the instructor's skills, and (iii) practice, and is then mathematically modeled. STBO performance is evaluated on twenty-three objective functions of the types of unimodal, high-dimensional multimodal, and fixed-dimensional multimodal. The optimization results show that STBO, with its high power of exploration and exploitation, has provided suitable solutions for benchmark functions. Also, to evaluate the quality of STBO, the results are compared with ten well-known metaheuristic algorithms. Furthermore, the simulation results show that STBO has a much more competitive performance than competitor algorithms by providing superior results. Finally, the implementation of STBO in solving four engineering design problems demonstrates the capability of the proposed approach in dealing with real-world applications.
The aim of the paper is to generalize results by Sikorska on some functional equations for set-valued functions. In the paper, a tool is described for solving a generalized type of an integral-functional equation for a set-valued function F:X→cc(Y), where X is a real vector space and Y is a locally convex real linear metric space with an invariant metric. Most general results are described in the case of a compact topological group G equipped with the right-invariant Haar measure acting on X. Further results are found if the group G is finite or Y is Asplund space. The main results are applied to an example where X=R2 and Y=Rn, n∈N, and G is the unitary group U(1).
