Probabilistic Behaviour in Ants: A Strategy of Errors?
ثبت نشده
چکیده
Animal behaviour is probabilistic. This is exemplified by the communication behaviour of ants during food-searching. Experimental evidence demonstrates that species differ in the accuracy of their recruitment. We show here, with the help of a very simple mathematical model, that the randomness of behaviour can have an adaptative advantage for ants. The model demonstrates that the degree of randomness could be optimally "tuned" to particular ecological conditions, such as food quantity and distribution.

Rationality in collective decision-making by ant colonies.
Economic models of animal behaviour assume that decision-makers are rational, meaning that they assess options according to intrinsic fitness value and not by comparison with available alternatives. This expectation is frequently violated, but the significance of irrational behaviour remains controversial. One possibility is that irrationality arises from cognitive constraints that necessitate ...
متن کاملProbabilistic Optimal Operation of a Smart Grid Including Wind Power Generator Units
This paper presents a probabilistic optimal power flow (POPF) algorithm considering different uncertainties in a smart grid. Different uncertainties such as variation of nodal load, change in system configuration, measuring errors, forecasting errors, and etc. can be considered in the proposed algorithm. By increasing the penetration of the renewable energies in power systems, it is more essent...
متن کاملProbabilistic GENCOs Bidding Strategy in Restructured Two-Side Auction Power Markets
As a matter of course, power market uncertainties escalation is by product of power industry restructure on one hand and the unrivalled penetration of renewable energies on the other. Generally, the decision making process in such an uncertain environment faces with different risks. In addition, the performance of real power markets is very close to oligopoly markets, in which, some market play...
متن کاملA New Approach for Sequencing Loading and Unloading Operations in the Seaside Area of a Container Terminal
Due to the considerable growth in the worldwide container transportation, optimization of container terminal operations is becoming highly needed to rationalize the use of logistics resources. For this reason, we focus our study on the Quay Crane Scheduling Problem (QCSP), which is a core task of managing maritime container terminals. From this planning problem arise two decisions to be made: T...
متن کاملBacktracking behaviour in lost ants: an additional strategy in their navigational toolkit.
Ants use multiple sources of information to navigate, but do not integrate all this information into a unified representation of the world. Rather, the available information appears to serve three distinct main navigational systems: path integration, systematic search and the use of learnt information--mainly via vision. Here, we report on an additional behaviour that suggests a supplemental sy...
