Algorithms • A rule that guarantees the right solution to a problem. • Usually by using a formula. • They work but are sometimes impractical.

Heuristics • A rule of thumb that generally, but not always, can be used to make a judgment to solve a problem. • It is fast, but is… • Prone to errors • Two major types of heuristics….

Representativeness Heuristic Who went to Harvard? Dan is a smart dude, but did not go to Harvard (but he looks like he did). • If I tell you that Sonia Dara is a Sports Illustrated swimsuit model, you would make certain quick judgments (heuristics) about her…like about her interests or intelligence. • She is an economics major at Harvard University. • Judging a situation based on how similar the aspects are to the prototypes. • E. G. - thinking everyone from NFHS is a redneck/hunter, or someone with glasses is nerdy, or a blonde is not smart.

Availability Heuristic • Judging a situation based on the availability of information in memory. Which city has the highest murder rate? New York, NY The crime rate of Philadelphia, PA is much higher than that of New York City. Click here for the 2013 stats. Philadelphia, PA

One day, as you walk through the commons, you find this key. How would you use an algorithm to find the lock to which this key belongs? What about a heuristic?

Hurdles to problem solving

Mental set your “formula” for success in a regular class vs AP • a. k. a. rigidity • The tendency to fall into established thought patterns.

Functional Fixedness (example of mental set) • The inability to see a new use for an object. Think of as many uses as you can for a ……

Confirmation Bias • Looking for evidence to confirm our beliefs and ignore evidence that contradicts them. • i. e. - One believes that all Italians are in shape and go tanning, then they turn on MTV. Look…I knew it was true!!! But is it really?

Framing • • 90% of the population will be saved with this medication…. . or 10% of the population will die despite this medication. You should not drink more than two drinks per day…. or You should not drink more than 730 drinks a year. Look at the following question and think about how the question is worded may effect the way it is answered. • How can businesses become more socially responsible? • The way a problem is presented can drastically effect the way we view it.

Overconfidence • Our confidence is not a good indicator of how right we are. • Belief Bias- People will tend to accept any and all conclusions that fit in with their systems of belief, without challenging or seriously considering what it is they believe • Belief Perseverancemaintaining a belief even after it has been proven wrong

Artificial Intelligence • designing computer systems to simulate human thinking and do intelligent things • computer neural networks – computer circuits that mimic the brain’s neural cells, performing tasks such as learning to recognize visual patterns or cells
