The evolutionary approach called scatter search originated from strategies for creating composite decision rules and surrogate constraints. Recent studies demonstrate the practical advantages of this approach for solving a diverse array of optimisation problems from both classical and real world settings. Scatter search cont rasts with other evolutionary procedures, such as genetic algorithms, ...

In this study, we proposed an improved LPP method named Scatter-Difference Discriminant Locality Preserving Projection (SDDLPP). It considers discriminant information by maximizing the scatter-difference, which makes it have better classification capability. SDDLPP also avoids the singularity problem for the highdimensional data matrix and can be directly applied to the small sample size proble...

For a sample of 51 blazars with extensive optical polarization data, we used circular statistics to calculate the scatter among the polarization position angles for each object. We found that this scatter is correlated with the radio core dominance. We compared this relationship with the predictions of a simple transverse shock model. The result suggests that blazar jets are likely to cover a w...

This report describes the analysis of results of a Lincoln Laboratory experiment which consisted of a series of bistatic scatter and radar measurements of the scattering cross section per unit volume of rain and thin turbulent layers. Results of tbe experiment are presented as average and rms values of the ~ of the bistatic scatter cross section as calculated using the radar data to the cross s...

An important distinction of diffusion models is that they only model multiple scattering. We generally distinguish between scatter events at different path depths: Zero-scatter events are photons that enter a surface and immediately reach an exit point without having scattered in the medium itself. Single scatter events do the same with a single interaction inside the volume. Multiple scatter e...
