Graph Structures

Create a Data Structure for Linked Data

Exploration

• Read chapters 20 and 21 in A First Course on Data Structures in Python
• Explore directed and un-directed graph implementations in the ds2 package of donsheehy/datastructures.
• Review previous chapters to see how the data structures like List and Tree support the behavior of this data structure.

Activities

• Monday and Wednesday: Graph Structures
  • Explore how to implement the Graph and Digraph data structures
  • Understand the adjacency list and adjacency matrix representations
  • Examine Python source code segments to illustrate key points
• Thursday: Continue an algorithm engineering project
• Friday: Team-work on final algorithm all-hands projects

Project

Goal

To build and use a Python program, called treesearcher, that runs benchmarks to study the performance of finding data values in a hierarchical data structure.

Steps

• Use treesearcher as your template repository
• Install the project’s dependencies using devenv
• Follow the instructions to complete the project:
  • Week 1: Implement all of the modules in treesearcher
  • Week 2: Design and conduct experiments and document experimental results
• Schedule office hours if you have questions
