Implementing A* search algorithm

Needed in 2 days max.. For this project we will be working in three steps, the project is : Implement A* search algorithm and its variations (i.e. IDA* and SMA*). Suggested data: Run on the US major freeways network (or any other problem of your choice). Be aware of memory-complexity! ( the data have to be accessible ) Experiment on these different variations/improvements for time and memory consumption. First step: Report: Which 3 algorithms will you use? Which language will you use to code? If you decide to use some code, what is the source of that code, and how will you modify that code for your project (must)? Which data will you work on? Briefly describe the design of your experiments, what will you measure, how many times you will run the code, etc.? ** these two steps to be done later: Second step: Report on algorithms and codes Third: Final report on experimental result
