Study Notes
- The course packet defines algorithms and their importance and application
- It explores problem analysis phases and computing problem types
- Students will write algorithms as pseudocode/flowcharts
Course Packet Goals
- Explain algorithm design phases
- Explain analysis process
- Explain various problem types
Group Activity: Old World Puzzle
- A puzzle involving a peasant, wolf, goat, and cabbage is presented
- The peasant needs to transport all three across a river
- The boat can only hold the peasant and one other item
- The wolf would eat the goat, and the goat would eat the cabbage if left unattended
- The challenge is to solve the puzzle or prove it impossible, given that the peasant is vegetarian and dislikes cabbage, and the wolf is a protected species
Problem Definition
- A problem is a statement about objects/structures needing solutions or explanations
Problem Specifications
- Input instances must be specified
- Output should be specified in terms of the input
Sorting Problem
- Input: A sequence of n numbers {a1, a2, ..., an}
- Output: A reordered sequence where a1 <= a2 <= ... <= an
