The real-life context of this model could be of different variations on motion in hiking or some other outdoor adventure sport. HOW IT WORKS ------------ When setting up the model, two turtles are created. One that has a random heading that travels randomly as well. While the other turtle goes straight. In the procedures is code for creating peaks (or heightened patches). The object in this model is to see what turtle succeeds in traveling with the most height. The number of peaks can be controlled by a sliding bar. I have a variable: height and global variables: maxheight, turt0total, turt1total, turt0avg, turt1avg, turtle1 and turtle2. I use the height variable for the height of ecah patch, the maxheight variable for how high the highest peak is, turt0total holds the sum of the heights that Turtle 1 (referred to as 0 in code) makes as each tick goes on (the same applies to Turtle 2 (referred to as 1 in code, and the variable turt1total). 'turt0avg' and turt1avg are variables that give the average height covered over many ticks. 'turtle1' and turtle2 are variables that say what the height is that the turtle is on (it is used in plotting graphs for Turtle 1 and Turtle 2). HOW TO USE IT ------------- To start, the model has the SETUP MODEL button which initializes the model. The height of the highest peak (maxheight) is random every time. There is a slider button that says NUMBER, meaning the number of peaks that are generated when you SETUP MODEL. Slide the bar back and forth to eiher decrease or increase the number of peaks. The START MODEL (1-STEP) button moves the model through one 'tick' of progress. The START MODEL (INFINITE) button moves the model continously. A HEIGHT OF THE HIGHEST PEAK monitor is given for the observer. TURTLE 1 TOTAL HEIGHTS REACHED is a monitor which states the (increasing) sum of heights that Turtle 1 travels at each peak. The same goes for TURTLE 2 TOTAL HEIGHTS REACHED. TURTLE 1 AVG is a monitor that gives the average of total height traveled divided by the ticks progressed. The same goes for TURTLE 2 AVG. Finally, there is some graphical representation of the data collected. Two graphs are shown on the interface: 'turtle1' graph which plots ticks on the x axis and the height traveled at each respective tick on the y axis. The same design applies to the 'turtle2' graph. THINGS TO NOTICE ---------------- Notice that because of the differing headings of Turtle 1 and Turtle 2, Turtle 1 which moves randomly always has the higher amount of height traveled and averaged. THINGS TO TRY ------------- Try to vary the number of peaks and compare how fast the turtles gather height as compared to other amounts of peaks. EXTENDING THE MODEL ------------------- To extend the model, I was thinking of adding another (one or more) motion behaviors which can affect turt0total & turt1total. Also, along with those additional behaviors, figuring out how to make each turtle have an 'on/off' switch for easy comparison would be an appropriate addition. NETLOGO FEATURES ---------------- An interesting feature of NetLogo in this model is the color gradation that is used for the peaks. You can easily make the color represent differences (for this example in height of peaks with this model) in how high each patch particularly is by what color green it is. Autoplotting the two graphs is a great, handy feature that NetLogo has as well as the ability to change the graphic of the turtle (which is better for representation).
