A framework for conducting agent-based simulations of SETI

Project description

This Python package allows the user to setup and run an agent-based simulation of a SETI survey. The package allows the creation of a population of observing and transmitting civilisations. Each transmitter and observer conducts their activities according to an input strategy. The success of observers and transmitters can then be recorded, and multiple simulations can be run for Monte Carlo Realisation.

This package is therefore a flexible framework in which to simulate and test different SETI strategies, both as an Observer and as a Transmitter.

Features

  • Object-oriented, agent-driven simulation of Observers and Transmitters

  • Simulates continuous and pulsing broadcasts at a defined beam-size

  • Permits transmission/observation as a scan across the sky, or as a series of discrete pointings

  • Accounts for Doppler drift due to transmitters/observers orbiting a host star

  • Generates maps of the sky as seen from Observers’ point of view

Future Features/Wishlist

  • Currently designed for electromagnetic communications - in principle extendable to e.g. neutrino or gravitational wave emission

  • Interstellar scintillation/absorption/dispersion

Installation Instructions

This package is yet to be hosted on PyPI…

Examples of Use

Examples of how to use tak-tent to setup and conduct SETI simulations can be found in the src/examples/ folder.

Package Structure

The package contains several modules defining six fundamental classes:

### agents/

Vector3D - a 3D cartesian vector class

Agent - a generic agent base class

Transmitter(Agent) - a transmitting civilisation

Observer(Agent) - an observing civilisation

### strategies/

Strategy - a base class that defines generic targeting behaviour of an agent as a function of time

PointingStrategy(Strategy) - A discrete pointing strategy (defined by a list of target vectors) scanningStrategy(Strategy) - A continuous pointing strategy (defined by a target vector function)

### population/

Population - a class that defines the combined population of Transmitters and Observers, and drives the simulation

Code dependencies

The code has been developed in Python 3.6, using numpy 1.14.3 and matplotlib 2.2.2

The Name

The name “taktent” is derived from the Scots phrase “tak tent o’ the sma things”, which translates as “pay attention to the little things”
