The real-life optimization problems are too complex to be solved by developing a mathematical formula. Heuristic methods the defined decide best of variety solution actions solve problem. Furthermore, it is preferred that heuristic short in time and can applied different problems. were developed while trying find solution. created algorithm, which was based on herd intelligence, used behaviors ...

In recent years, various heuristic optimization methods have been developed. Many of these methods are inspired by swarm behaviors in nature. In this paper, a new optimization algorithm based on the law of gravity and mass interactions is introduced. In the proposed algorithm, the searcher agents are a collection of masses which interact with each other based on the Newtonian gravity and the la...

This technical note presents a behavior-based navigation method for a mobile service robot with a three-wheeled omnidirectional mobile platform. A heuristic fuzzy Kohonen clustering network (FKCN) is presented to obtain laser area weights and desired robot motion heading for all types of indoor environments. An efficient behavior-based navigation structure is then proposed to merge the heuristi...

We study the approximation properties of pseudo-differential operators with small time-frequency dispersion, meaning that their spreading functions are supported in a neighborhood origin. It is commonly assumed for such H, output Hf can differ only little from scalar multiple input f. However, we disprove this heuristic statement using theory superoscillations. This reveals some unexpected beha...

Under partial shading conditions (PSCs), photovoltaic (PV) generation systems exhibit multiple local and a single global maximum power point. Consequently, point tracking (GMPPT) is required to improve the performance of PV in such scenarios. This paper comparatively studies evaluates modern heuristic-optimization-based GMPPT techniques. Monte Carlo method used statistically analyze different m...

Soldiers’ group behaviors are a class of flocking behaviors in which a squad of soldiers march forward according to a specified formation and try to keep it when encountering narrow corridors. It has a leading application in deterring the behavior and activities of a potentially hostile crowd and bringing a mob engaged in a riot under control in social stable maintenance. In this paper, we focu...

Behavior-based robot programs are designed by splitting the overall robot decision making process among concurrent processes, each of them being in charge of a well defined simple goal-oriented behavior. However, the combination of simple behaviors into more complex ones often incur global interactions that cannot be debugged by just considering individual behaviors. The normal way of dealing w...

Behavior analysis of credit cardholders is one of the main research topics in credit card portfolio management. Usually, the cardholder’s behavior, especially bankruptcy, is measured by a score of aggregate attributes that describe cardholder’s spending history. In real-life practice, statistics and neural networks are the major players to calculate such a score system for prediction. Recently,...

in recent years, size of vlsi circuits is dramatically grown and layout generation of current circuits has become a dominant task in design flow. standard cell placement is an effective stage of physical design and quality of placement affects directly on the performance, power consumption and signal immunity of design. placement can be performed analytically or heuristically. analytical placer...

Scheduling conditional behaviors necessitates the use of a variety of scheduling optimization techniques like conditional resource sharing and speculative execution. Previous research work has clearly shown their effectiveness. The developed heuristics have several drawbacks relating to the effects of syntactic variance on the results. In this paper a list-based scheduling heuristic that exploi...
