Sociodynamica 1 simulates the economy of a territory with two resources, food and minerals. The inhabitants or agents require to consume continually both to survive. Agents are omnipotent if they collect and market both resources. If division of labor is implemented, farmers specialize in collecting and selling food, miners collected and sell minerals, and traders buy and sell food and minerals but do not collect resources. Commerce consists of barter and the use of a virtual currency for the purchase and sale of resources.
The game displays unintuitive complex interactions, such as the relationship between pricing, maximizing wealth (accumulated resources) and maximization health (measured by agents average life).
Recommended Games
Solitaire:
1- Find the optimal conditions of the variables, fixing the amount of minerals and food for different run times.
2- Find the optimal conditions of the variables, fixing the amount and price of minerals for different run times
3- Design a temporary program in the value of the variables to optimize vital wealth and welfare simultaneously
Optimum = average life * (amount of mineral + amount of food)
Two players:
A player sets economic variables minerals, other economic variables fixed meal. Farmers and miners competing to get the most of your resource (Food and minerals, respectively).
World Competition
Be recognized as the best gamer in the World (Emperor, Sultan, King, President or Chancellor of Sociodynamica) by sending the combination of variables that optimize the game for 60 # areas of Minerals and 90 # areas of Food. Send your chosen values to cee-usb.ve with your name. Tournaments with 100 randomly selected scenarios will update the winner every month.

Sociodynamica (detailed description)
Input data:
The left vertical bar allows to input the parameters for the simulation using the slider controls. The first is the "Contact radius”, or the radius of the area where the agent can perform commercial transactions. The second indicates the amount to be used for the "Price adjustment" after a failed transaction, where 0 is used to simulate fixed controlled prices. The third variable is a 'check-box' or control to chose whether "Division of labor" will be simulated. That is, whether all agents have the same characteristics (they are all Omnipotent), or the roles as a Farmer, Miner or Trader are performed by different agents. Farmer can only collect food, Miners collect only minerals and Traders trade but do not collect any resource. Then there are two sets of controls: one for "Minerals" and another for "Food". In each case you can set the starting “Price” of the resource; the minimum amount of resource that is never traded because it is maintained as a "Reserve" by the agents; and the number of "areas" that contain the resource.
Displaying the Simulation
In the simulation, areas with food and minerals are shown in orange and blue respectively. These are randomly generated in each simulation according to the "# areas of food and minerals" defined in the input data. A button allows you to "Create" a new simulation scenarios whenever you want, and another one allows you to "Run" or "Stop" the simulation. In "Steps"the number of iterations performed in the simulation is shown.
Viewing Results
On the right side of the screen three graphs summarize the relevant parameters (average and last value generated) for all active agents shown. The figures for food are in orange and blue figures correspond to minerals. The first chart from top to bottom, shows the accumulated wealth for food and minerals at the end of each iteration. The second chart shows the average price of food and minerals used b agents in their commercial interactions. The third figure shows the average age of the surviving agents (low average age is due to high mortality).
Description
Each agent at birth has 10 units of money, and as much wealth in minerals and food. It is located in a randomly selected place and does not move. When the coordinates coincide with a food source or mineral resource, the agents may collect 2 units in each iteration. The resources are inexhaustible. Baseline consumption for each agent for both mineral and food is 1 unit for each iteration. If the agent is left without food or mineral, it dies and their values are discarded. If the agent remains alive and has an excess supply of food and/or minerals, it look for neighbors in the "Radio contact" for commercial transactions. In each transaction it tries to buy/sell under the following conditions:
Food, if the seller is omnipotent and buyer is omnipotent.
Food, if the seller is a farmer and the buyer is a miner or trader.
Food, if the seller is a trader and the buyer is a miner.
Minerals, if the seller is omnipotent and buyer is omnipotent.
Minerals, if seller is a miner and the buyer a farmer or trader.
Minerals are sold by trader to farmers and other traders.
The transaction is completed if the seller has more goods than it has in reserve, if the buyer has enough money and if the price at which the seller is willing to sell is less than or equal to the price the buyer is willing to pay. In this case, goods between seller and buyer are exchanged: the seller's resource maney is increased and that of the buyer decreased. The simulation shows the aggregate amount of food and minerals held by agents. The agent's width is proportional to the square root of it food. The height of the agent is proportional to the square root of its mineral wealth.
Market Rules
If a commercial transaction failed, prices are adjusted: Te seller lowers its price in the amount indicated by the variable "price adjustment" and the buyer raises its price it is willing to pay in the same amount.
Goal
Maximizing the average life of the agents, and the accumulated amount of food and minerals.
