Coverage-based Greybox Fuzzing (CGF) is a practical and effective solution for finding bugs vulnerabilities in software. A key challenge of CGF how to select conducive seeds allocate accurate energy. To address this problem, we propose novel many-objective optimization solution, MooFuzz, which can identify different states the seed pool continuously gather information about guide schedule energ...

Team composition is one of the most important and challenging directions in recommendation problem. Compared with a single person, advantage team mainly reflected synergy members' complementary collaboration. To build high-efficiency team, how to choose members has become tricky However, there lack quantitative algorithms validation methods for member selection. In this paper, we put forward th...

Recently, with the development of mobile devices and crowdsourcing platform, spatial (SC) has become more widespread. In SC, workers need to physically travel complete spatial–temporal tasks during a certain period time. The main problem in SC platforms is scheduling set proper achieve based on different objectives. actuality, real-world applications optimize multiple objectives together, these...

Walking mechanisms are a solution for cases in which wheels not applicable, such as uneven or stepped surfaces and withobstacles. Furthermore, it is possible to tailor mechanism footpaths expected working conditions through optimization. Thus, this paper, optimization process was proposed, focusing on single-leg performance. Numerical Simulink calculations were used determine objective function...

Evolutionary multi-objective optimization (EMO) found applications in all fields of science and engineering. Chemical engineering discipline is no exception. Literature abounds on EMO with a variety algorithms proposed by few dedicated researchers. The Nondominated Sorting Genetic Algorithm (NSGA-III) the latest addition to family EMO. NSGA-III claims have solved multi many-objective problems u...

Optimizing the location of physical activity spaces (PAS) to ensure health, equity and efficiency has long been an important issue in urban planning. Given health benefits green (UGS), taking Gongshu District Hangzhou as a case, we examine where such PAS should be located optimize three objectives: (1) minimize distance between UGS; (2) maximize accessibility (3) population that falls within co...
