Installing LogoLife

To install LogoLife, simply copy the LogoLife folder to your hard disk. You do this by dragging the LogoLife folder to your hard disk icon. Once the folder is copied to your hard drive, you are ready to go. If you downloaded LogoLife, then you got a ZIP file. Just unzip the contents of the file onto your hard drive and you are ready.

Running LogoLife

Running LogoLife is as simple as installing it. You simply open the LogoLife folder that you copied to your hard drive by double clicking on it. Inside this folder you will find the LogoLife application. Double click on the LogoLife application icon. This will cause the LogoLife program to be launched and the LogoLife menus to be displayed in the menu bar.

To begin a new population of LogoLife turtles, you must select the New Population item in the File menu. This will first display a dialog box that allows you to control the population's characteristics. You can accept the default values. Click the Ok button. This will open a new population window, in which turtles will be randomly created, and each turtle will display its figure in a small square.

It will take some time, depending on the complexity of each turtle's algorithm, to draw all of the figures for the entire population, so please be patient while this is done. You may click in other applications during this time, and LogoLife will compute the figures in the background.

The Population Window

The Population Window is a non-scrollable, fixed size window, which will display turtle figures. When a new population is evolved, the window will display all of the population's figures in small rectangles arranged in rows and columns.

You left-click on a particular figure to make that figure's turtle the currently selected turtle. The selected turtle is identified by a black border around the figure of the turtle to distinguish it from the other turtles.

A selected turtle may have several operations performed upon it. For instance, you may have the turtle's figure blown up to be displayed in the full contents of the population window. This allows you to inspect the finer details of the turtle's figure. You can also print a turtle's figure, save its algorithm to a file, or copy a turtle to the clipboard. Once on the clipboard, you can paste a turtle's drawing into any other Windows program, or you can paste it into another turtle's square (competition and survival). You may also dope a selected turtle with another turtle's algorithm that was earlier saved to a file, and finally, you may mutate a selected turtle to change its algorithm, and thus, its figure.

Notice that there is a border around the figure of all of the turtles. If the border is blue, then it is an indication that the turtle is currently chosen to participate in the reproduction of the next generation of turtles, based on its calculated fitness. If the border displayed around a turtle is red, then it will not be chosen for reproduction to create the next generation of turtles.

You can choose all turtles for participation in the next generation using the Choose All Turtles command in the File menu. You may chose none of the turtles for participation in the next generation by selecting the Chose No Turtles command in the File menu.
