CS 1025 01 - Week #7 - Oct 1, 3, 5

1. Shodor Data Flyer tool used to Plot Data.

       x	            y
   -----------     -----------
   18.87621698	182.4256292
   17.54633109	169.9205046
   14.61456355	142.5921396

   13.48852953	134.4956086
   20.67813062	200.9475343
   23.37232677	233.8143082
   31.79632818	321.4977419
   22.29991883	220.8607116

   For the above set of numbers, use the DATA FLYER application.
         Assume that the INTERCEPT b can be left at 0.  
         It actually is 0 for this data!
         y = mx + b
         y = mx
   
         f(x) = m * x 
   
         What value of m, in other words, 
         what SLOPE 
                    gives you the SMALLEST SUM OF SQUARES OF DEVIATIONS?
   
         What is the slope of the BEST FITTING line for the set of 12 
                     -----                               (x, y) pairs?
   
   What is the SLOPE of the line that gives 
                              the smallest sum of squares of deviations?
   

2. Introduction to Cellular Automata: Oil Spill Percolation Model: Fixed rules (Fractals) versus random chaos.

   Compare to the LIFE model from NetLogo. How many neighbors does each CELL have? Stay alive, become alive, die off, stay empty (unpopulated). What happens to each CELL in the Game of Life?

3. Flash ActionScript and the bouncing ball. Gravity to be simulated using Adobe Flash. A very simple model will be created.

4. TEST ONE on Monday, October 8th: Study guide/outline practice questions for test #1:

5. Another set of practice data for the SHODOR data flyer application....

        x              y
   -----------     -----------
   20.44712727	20.51518572
   16.71315584	15.42506731
   17.99293085	16.15964686
   23.362533	22.79563739
   24.9267934	22.01796826
   18.55425506	18.20021532
   23.79604137	21.90370105
   19.86663545	17.55227197
   19.1290307	19.0699128
   21.91487095	22.91732607
   
       y = mx + b or in Data Flyer  f(x) = m * x + b
   
   
       What is m?   _________________       What is b?   _________________
   
   
       What is the Sum of squares of deviations that you found?
   
   

6. Follow the Mouse and Paint it Red: NetLogo fun.
