Starting and Sustaining Genetic Support Groups

Sustaining Cooperation in Heterogeneous Groups

The public goods game has been studied extensively in the lab as the quintessential model of a social dilemma. Several mechanisms have been demonstrated to promote group cooperation in linear voluntary contribution experiments – such as communication, costly punishment, and centralized bonuses and fines. However, lab experiments have largely neglected a central obstacle to e cient public good p...

Recurrent Genetic Algorithms: Sustaining Evolvability

This paper proposes a new paradigm, referred to as Recurrent Genetic Algorithms (RGA), to sustain Genetic Algorithm (GA) evolvability and effectively improves its ability to find superior solutions. RGA attempts to continually recover evolvability loss caused by the canonical GA iteration process. It borrows the term Recurrent from the taxonomy of Neural Networks (NN), in which a Recurrent NN (...

Sustaining Livelihoods through Animal Genetic Resources Conservation

Monthly rainfall Forecasting using genetic programming and support vector machine

Rainfall and runoff estimation play a fundamental and effective role in the management and proper operation of the watershed, dams and reservoirs management, minimizing the damage caused by floods and droughts, and water resources management. The optimal performance of intelligent models has increased their use to predict various hydrological phenomena. Therefore, in this study, two intelligent...
