Problems solved by technology

One of the problems with studying life sciences is that changes in ecosystems and the evolution of life forms takes place over long periods of time.
Use of physical robots to simulate large populations is impractical, as the robots will suffer from wear and tear, break downs, and require significant capital and support costs.

Embodiment Construction

[0024] The preferred embodiment utilises a large scale low fidelity simulation (Lo-Fi Sim) arranged to simulate the activities of a large number of animats. Such a Lo-Fi Sim is typically used to simulate at least 10,000 animats, but could for instance be utilised to simulate even larger numbers e.g. 100,000, 1,000,000, 10,000,000 animats or greater.

[0025] The Lo-Fi Sim (shown in FIG. 1 as step 100) is arranged to provide a simulation utilising good approximations of the macroscopic behaviour of an animat.

[0026] The Lo-Fi Sim has programmatic access to a simulation capable of modelling a small number of animats in greater detail, using all relevant physical details in a high fidelity simulation (the Hi-Fi Sim, 120).

[0027] The Lo-Fi Sim (100), utilising the macroscopic parameters is adequate at describing the animat during most of the simulation. However, when the animat encounters a change in its environment (110) that can not be adequately modelled using the Lo-Fi Sim then the Hi-Fi...

Abstract

A technique for simulating the activities of a large number of creatures is described. The technique utilises two modes of simulation. The first mode of simulation is arranged to simulate the activities of all of the creatures. The second mode of simulation is arranged to simulate the activities of a few of the creatures, at a more detailed level than the first mode. The second mode is utilised by the first mode to determine new parameters of individual creatures when the creatures undergo a change in environment.

Description

[0001] The present invention relates to a method and a device suitable for simulating the activities of a plurality of creatures.[0002] One of the problems with studying life sciences is that changes in ecosystems and the evolution of life forms takes place over long periods of time. Consequently, life processes have been simulated in a variety of formats, thus allowing the study of the interaction of creatures and the emerging population patterns.[0003] An animat is an artificial creature which exhibits an active and purposeful behaviour in an environment which presents it with problems--obstacles, navigation, hazards, goals. Animats are often inspired by biological organisms, which are observed to solve complex problems in real physical environments. Indeed, animats may be designed to be as close as possible to the original biological organisms, so as to model the potential behaviour and / or evolution of such organisms.[0004] Although it is possible to build physical robots to stud...
