Supersonically Induced Gas Objects (SIGOs) are a class of early Universe objects that have gained attention as potential formation route for globular clusters. SIGOs only recently begun to be studied in the context molecular hydrogen cooling, which is key characterizing their structure and evolution. Studying population-level properties with cooling important understanding collapse star formati...

In this paper the Differential Evolution algorithm is deployed to the robotic path planning optimization problem for autonomous mobile vehicles. At this stage, the simulations consider the robot world with level surfaces and static obstacles , in which the optimization is performed off-line. The global objective is to evaluate the differential evolutionary algorithm in solving path planning pro...

–The evolutionary approach called scatter search, and its generalized form called path relinking, originated from strategies for creating composite decision rules and surrogate constraints. Recent studies demonstrate the practical advantages of these approaches for solving a diverse array of optimization problems from both classical and real world settings. Scatter search and path relinking con...

Biogeography-based optimization (BBO) has recently become popular in unmanned aerial vehicle (UAV) path planning. Similar to other evolutionary algorithms, the performance of BBO is affected when the parameter setting is not finely tuned. Therefore, the BBO parameters are optimized in this research particularly for application in UAV path planning. Each combination setting of parameters is simu...

Path-dependent impulse differential inclusions, and in particular, path-dependent hybrid control systems, are defined by a path-dependent differential inclusion (or path-dependent control system, or differential inclusion and control systems with memory) and a pathdependent reset map. In this paper, we characterize the viability property of a closed subset of paths under an impulse path-depende...

An approach named Class-Based Elitist Genetic Algorithm is presented in this paper. The test data is being generated for object-oriented programs using evolutionary techniques. A class-based algorithm derived from class control-flow graph (CCFG) is used for testing object-oriented software. Evolutionary techniques have been used for solving most of the software engineering problems. Evolutionar...

We have found a new evolutionary path to Type Ia supernovae (SNe Ia) which has been overlooked in previous work. In this scenario, a carbon-oxygen white dwarf (C+O WD) is originated, not from an asymptotic giant branch star with a C+O core, but from a red-giant star with a helium core of ∼ 0.8− 2.0M⊙. The helium star, which is formed after the first common envelope evolution, evolves to form a ...

This paper demonstrates a new approach to multidimensional path planning that is based on multiresolution path representation, where explicit configuration space computation is not required, and incorporates an evolutionary algorithm for solving the multimodal optimization problem, generating multiple alternative paths simultaneously. The multiresolution path representation reduces the expected...
