A NOVEL MONARCH BUTTERFLY OPTIMIZATION WITH GLOBAL POSITION UPDATING OPERATOR FOR LARGE-SCALE 0-1 KNAPSACK PROBLEMS

A Novel Monarch Butterfly Optimization with Global Position Updating Operator for Large-Scale 0-1 Knapsack Problems

As a significant subset of the family of discrete optimization problems, the 0-1 knapsack problem (0-1 KP) has received considerable attention among the relevant researchers.The monarch butterfly optimization (MBO) is a recent metaheuristic algorithm inspired by the migration behavior of monarch butterflies.The original MBO is proposed to solve con

Astronomical Signatures of Dark Matter

Several independent astronomical observations in different wavelength bands reveal the existence of much larger quantities of matter than what we would deduce from assuming a solar mass to light ratio.They are very high velocities of individual galaxies within clusters of galaxies, higher than expected rotation rates of stars in the outer regions o
