Solving matrix games with hesitant fuzzy pay-offs

The objective of this paper is to develop matrix games with pay-offs of triangular hesitant fuzzy elements (THFEs). To solve such games, a new methodology has been derived based on the notion of weighted average operator and score function of THFEs. Firstly, we formulate two non-linear programming problems with THFEs. Then applying the score function of THFEs, we transform these two problems in...

Matrix Games with Trapezoidal Fuzzy Pay Offs

An approach for solving a matrix game whose pay off elements are symmetric trapezoidal fuzzy numbers is proposed. P.Grzegorzewski’s theorem[1]has been used to transform symmetric trapezoidal fuzzy numbers to interval fuzzy number such that length of all intervals are different.Acceptability index has been defined and ordering of fuzzy numbers has been established.

Correlated pay-offs are key to cooperation.

The general belief that cooperation and altruism in social groups result primarily from kin selection has recently been challenged, not least because results from cooperatively breeding insects and vertebrates have shown that groups may be composed mainly of non-relatives. This allows testing predictions of reciprocity theory without the confounding effect of relatedness. Here, we review comple...

Red List reveals conservation pay-offs

The protocol states that approval from the provider must be obtained before a genetic resource is used in a product and that, in each case, contracts governing the distribution of benefits should be agreed by provider nations and users. User nations are obliged to establish at least one organisation to check that proper procedures are followed and prevent the illegal use of genetic resources. I...
