BUILDING A COMMUNITY OF COMPUTATIONAL THINKERS Wayne Patterson Howard University

This course is now in the catalog as SYCS 501, 3 credits Being offered this Fall CIRTL Students + others Math Department has asked for a variation of this course (probably at a 1-credit level) for Spring 2011

There are: 365 days in a year 25 people in a group So whats the chance that for a given group of 25, two people will have the birthdate (not necessarily the same year)? 365 days …………. 25 people ……. 25 365 = 6.8% Something that occurs with 6.8% probability occurs once every 14.6 times

Hopes for the Course Think of a question where your first instinct is a qualitative analysis Learn how to recast the problem computationally Acquire some tools to facilitate the computations Design approaches to teaching the computational approach Carry out the computational solution and the TAR approach

Example 2: Oprah Winfreys Cars There is a lady named Oprah She has a television show She gives away cars to some of her fans But she has a problem She only has ten shows left before she retires But she has 500 cars to give away But being a fair person, she doesnt want to give an additional car to one of her audiences that increase the ratio between the number of persons per car

SOLUTION: The Oprah-Huntington-Hill Algorithm

Example 3: Counting Heads How do we take a census? 1, 2, 3, 4, … HTC Tracts What are they, where are they, how big are they Undercount How to estimate it, whats the potential cost Sampling techniques

Example 4: Pay Baseball Players or Soccer Players? I use some of my retirement income and buy the New York Yankees and Manchester United Will I get a better return (in terms of wins) by paying higher salaries to my baseball team or my soccer team?
