Evolution window

The evolution space is controlled by a NSView object assigned to the Evolution window, the window is resizable over all the screen. One current and important problem in the system is that the initial configuration is limited by the resolution of the screen.

Another relevant detail is that the system does not determine the size of the configuration introduced by the user, producing undesired structures in the limits of the configuration. In order to avoid these undesired structures in the evolution, one alternative is to fit manually the width of the Evolution window so that the regular expression defining ether finishes precisely in the last cell.

Figure 3: Evolution space

Figure 3 shows three evolutions in Rule 110, the first illustrates the evolution from a random configuration, in this example we have applied different colors to ether in order to get a better identification of the gliders or simply to obtain an attractive figure.

The second figure illustrates the evolution of a cell with state 1, this example is interesting because if the space is sufficiently large, it is possible to see how the produced margin also generates gliders gun, and in four thousand generations the evolution becomes periodic.

The third figure in a special case illustrating the construction of $\bar{\mbox{B}}^{2}$ glider. Two ether configurations are assigned using the panel of gliders, then an A glider in phase 2 is specified. The location of gliders and phases in the panel of gliders is by means of coordinates, first the user looks for the row of the A glider, then the user takes the column corresponding with phase 2 and this selection assigns the desired sequence, this process is used to yield the whole expression. In this example it is necessary to extract sequences which are not specified in the panel of gliders, for instance the group of A and B gliders must be assigned from the chain console. The reason of this problem is because the regular expressions are coded for a single glider and not for groups or extensions of them. In this case we have another problem due to the unlimited number of times in which they can be grouped or extended.
