Abstract | Artificial Agents infused with emotions have attracted considerable attention in recent years. Many domain areas require agents to be able to demonstrate an emotional reaction to stimuli, beliefs, goals, communication etc., thus exhibiting a believable behaviour. On the other hand, little has been said on how formal methods could integrate emotions in a form of rigorous mathematical notation. This paper is an initial attempt to infuse a formal modelling method for reactive agents, namely X-machines, with appropriate attributes that model artificial emotions. X-machines are finite state-based models extended with memory as well as functions that are applied on input and memory values. X-machines have been shown to be particularly useful to model reactive agents. The computation, that is the overall behaviour of an agents, is a sequence of states reached through the application of transition functions (actions that an agent performs). This computation is amended when artificial emotions are involved, thus leading to a different overall behaviour when an agent acts under artificial emotions. After discussing basic theories on emotions and their role to creating believable agents, we present the definition of the $^{e}X-machine$ $(^{e}χ)$ and its computation. A simple multi-agent system with emotional reactive agents is used to show the formal modelling process. Additionally, the same example is used to demonstrate how a visual simulation, based on $^{e}χ$ formal modelling, has different behaviour of the overall system, when artificial emotions are applied. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
