Competition and Selection Among Conventions

Rahmtin Rotabi, Cristian Danescu-Niculescu-Mizil, Jon Kleinberg
2017 Proceedings of the 26th International Conference on World Wide Web - WWW '17  
In many domains, a latent competition among different conventions determines which one will come to dominate.  ...  In this work we study a setting in which we can cleanly track the competition among conventions.  ...  We now consider the outcome of competition between two authors who have recently used different conventions for the same macro body.  ...

Competitive Strategies for Differential Evolution

Jun Yu, Yan Pei, Hideyuki Takagi
2018 2018 IEEE International Conference on Systems, Man, and Cybernetics (SMC)  
We introduce two competitive strategies into conventional differential evolution (DE) to speed up its convergence by increasing competitive pressures among individuals and evaluate the proposals.  ...  The experimental results indicate that properly enhancing competition among individuals in DE can speed up its convergence and improve optimization performance.  ...  ACKNOWLEDGMENT This work was supported in part by JSPS KAKENHI Grant Number 18K11470 and 17H06197.  ...

Channel Selection Policy in Multi-SU and Multi-PU Cognitive Radio Networks with Energy Harvesting for Internet of Everything

Feng Hu, Bing Chen, Xiangping Zhai, Chunsheng Zhu
2016 Mobile Information Systems  
In a multi-SU and multi-PU cognitive radio network, selecting channels is a fundamental problem due to the channel competition among secondary users (SUs) and packet collision between SUs and primary users  ...  Then we propose a competitive set based channel selection policy for multi-SU where all SUs competing for data transmission or energy harvesting in the same channel will form a competitive set.  ...  Hence, the channel competition among SUs will largely limit the performance of conventional random policy.  ...

Varieties for OA need efficient nutrient uptake and use and weed competition. These and other characters need to be considered in relation to the OA cropping system over the whole rotation.  ...  The wide range of environments within OA and between years, underlines the need to try to select for specific adaptation in target environments.  ...  The authors showed in particular that the average yield of the different populations increased over time as a result of natural selection and competition among plants.  ...

According to previous research, in interorganizational relations, selective ability and integration capability are important. It is thought that a high level of selective ability is very important.  ...  Then, there are two general possibilities for the form of open innovation: selection with a large network and a narrow network.  ...  The hypotheses about the organizational capability for IoT-related business (H5 and H6) were verified. The selection capability (H5) correlated with both conventional IT and IoT.  ...
