ComplekCity
A simple model of a city.
A city can function as an organism.
Each citizen is analogous to a cell and each business is a function of the body.
This model attempts to create a city that can live, expand or die.
The experiment tries to answer the question: What parameters make a city live?
Rules of ComplekCity:
The city:
- Consists of a road network, citizens and businesses.
- 1 minute = 1 day
- A business can mean government, restaurant or office.
- A point can mean money, food or energy.
- A city dies if all citizens or all businesses die.
A citizen:
- Has points which decrease linearly with time.
- Has eyes that can see a certain range.
- They always maintain a distance from any object in the city, including other citizens.
- Spawns at a random location in the city at 0 second.
- Every second, it notes down its location. This array of location points is called a path.
- Score of a path: max points in the day + average points in the day.
- Has history of the previous path and its best path.
- Visiting a business for 1 second will give him 2 points.
- Can choose to move in 3 ways:
- Previous path location at that second.
- Its best path location at that second.
- New path (random exploration)
- Choosing the path direction:
- If points are low, high probability towards its best path
- If points are moderate, equal probability
- If points are high, high probability towards a new path
- If points are > threshold, can open a business.
- Dies if points go to 0.
- If alive for 18 days, it makes 2 off-springs.
A business:
- A business has an owner who is a citizen or the government.
- When a citizen comes to a business, the citizen and the owner both get 2 points.
- If the owner's points go < threshold, the business no longer exists and the owner becomes a free citizen.
Changes planned for V2:
- Citizen moves at variable speed.
- Points decrease non-linearly with time depending on how fast it is moving.
- Remembers speed at the instant.
- Day and night cycles.
- Citizens sleep for half a day.
- Traffic lights.
- Multiple Lanes.
- Biased business (Ex: bars only for adults)
- Expand city if # of business > threshold.
