Abstract:
The paper describes a computer model for simulating the movement of diatom microalgae on the substrate surface. The model belongs to the class of agent-based models, which implements the behavior of virtual individuals simulating diatom microalgae. The individuals live in discrete time and move on a flat, continuous, bounded surface of a rectangular shape. Individuals are represented by figures with rigid boundaries that cannot be overlapped. At each moment of time, an individual can slide in one of two directions, rotate clockwise or counterclockwise, simultaneously slide and rotate, or remain motionless. The choice of an action is determined randomly. The probability of choosing each action is recorded in a parameter array, the genotype, available to all individuals. An individual can also remember a past action. Given a memory, it recalls and repeats the action with a given probability of repetition. These probabilities are also recorded in the shared genotype. The parameters in the genotype are not fixed, the user can customize them using interface elements. The paper shows how the trajectories of individuals vary at different values of the probabilities. The model is available at micro-algae.ru/diatoms/idm.
Keywords: organisms locomotion, diatoms, agent-based model, simulation model.
