There are approximately two million species of organisms in estimation today, each possessing different preferences
or tolerance towards a multitude of factors; these factors include mainly competition between species and environmental
conditions. From a computer modelling point of view, these biological systems could be difficult to implement.
However, if a unified formula could be found to measure all of the factors against the preferences of each life form, its potentials
for modelling open systems that require multiple external input variables could be significant. This article explores
a formula and variations of it as applied first to measure static (immobile) systems – vegetation, which requires multiple
variables for determining its fitness, and then to a pilot study exploring its use for dynamic (mobile) systems. Experiments
suggest that using the formula and variations of it on vegetation communities yielded distribution patterns similar to those
in natural landscapes. Experiments using the formula in the pilot study showed characteristics of emergent behaviours as
each dynamic system seeks its own ecological niche. The findings provided evidence that the formula could be extended
for modelling a wide variety of open biological systems.
