The hare and the tortoise: the network structure of exploration and exploitation

چکیده
We found a curvilinear relationship between density and final score. Moderately low density measures (p=.04-6) outperformed very low density graphs and higher density graphs. Graphs with very low density often contain isolated cliques that reduce average score. If all nodes are not connected, then they cannot share the best solution found, lowering the optimal score. Eliminating all multi-clique networks confirms a negative (monotonic) relationship between network density and average long-term solution. Since average path length is negatively correlated with density, this supports the hypothesis that higher scores are a function of higher distance between nodes. Random Networks (Erdos-Renyi) Results: Linear vs. full networks

Multi-objective Grasshopper Optimization Algorithm based Reconfiguration of Distribution Networks
Network reconfiguration is a nonlinear optimization procedure which calculates a radial structure to optimize the power losses and improve the network reliability index while meeting practical constraints. In this paper, a multi-objective framework is proposed for optimal network reconfiguration with the objective functions of minimization of power losses and improvement of reliability index. T...
متن کاملThe parable of the hare and the tortoise: Network
Networks provide the architecture of systemic adaptation. In any social system, the units of that system seek success—whether those criteria for success are determined by evolutionary processes or by (boundedly rational) goal-seeking processes. Networks provide the architecture of success in social systems because information about success that flows through the network provides one of the prim...
متن کاملAn Improved Bat Algorithm with Grey Wolf Optimizer for Solving Continuous Optimization Problems
Metaheuristic algorithms are used to solve NP-hard optimization problems. These algorithms have two main components, i.e. exploration and exploitation, and try to strike a balance between exploration and exploitation to achieve the best possible near-optimal solution. The bat algorithm is one of the metaheuristic algorithms with poor exploration and exploitation. In this paper, exploration and ...
