iGEM - Bordeaux - Conception
We choosed to create 4 operons:
The next figure represents the different genetic constructions that we will try to make.
Principle and rules
Each cell of the grid can be in 4 differents states: state1, state2, state3, state4 (state4 being state 1 and 2 at the same time). On the following steps the state of the cell is determined by the action of other close cells. The next rules are applied on each cells of the grid for each turn:
Definition of a “state”
A “virgin” cell has a state at 0 at the begining. Each cells have severals caracteristics wich are non activated when the simulation begin (excepted for their coordinate x and y). Exemple: Here is an exemple of a grid with x cells in beige:
Characteristics of the algorithm
Size of the grid : infinite, the size is choosed by the user (file init_PEB.py). Step of time (t) : new step of time correspond to the addition of the function stimulus_factor(). State of the cell :
