This paper presents a formal framework for modeling belief revision in cognitive agents, to integrate realistic epistemic dynamics in agent-based social simulation. Special emphasis is given to individual variation in MAS: agents are allowed to change their beliefs according to different cognitive styles, and such individual distinctions are captured and specified by the model. Although the fra...

Adequate operative field space minimises potential complications during revision knee arthroplasty. The colonisation rate of pneumatic re-useable devices reported to be 68-78%, other devices should be considered in the revision knee surgery setting. Sterile single use tourniquets devices (Heamaclear® /S-MARTTM, OHK Medical Devices, Haifa, Israel) have colonisation rates of 0%. This study assess...

Two trials were conducted to study the effect of multi-steps phase-feeding (PF) program on growth performance of broiler chickens from 1 to 24 and 1 to 39 d of age. The control group was the nutrient recommendation of Aviagen (2019) with a three-step PF program (1-10, 11-24 and 25-39 d of age). In the first trial, the control group was compared with an eight-step PF program (PF8), and in the se...

The success postulate of classic belief revision theory demands that after revising some beliefs with by information the new information is believed. However, this form of prioritized belief revision is not apt under many circumstances. Research in non-prioritized belief revision investigates forms of belief revision where success is not a desirable property. Herein, selective revision uses a t...

We propose a multi-agent genetic algorithm to accomplish belief revision. The algorithm implements a new evolutionary strategy resulting from a combination of Darwinian and Lamarckian approaches. Besides encompassing the Darwinian operators of selection, mutation and crossover, it comprises a Lamarckian operator that mutates the genes in a chromosome that code for the believed assumptions. Thes...

We address the issue of belief revision in a multi-agent setting. We represent agents' beliefs in a semantic manner, through a Kripke structure, and model a communication process by which agents communicate their beliefs to one another. We define a revision rule that can be applied even when agents have contradictory beliefs. We study its properties and show that agents need not agree after com...
