My Solution to A1
• Posted on web site
• slider.cpp.html
• Took me 140 minutes
• But I solved it once 13 years ago
• My run-time:
• For 5x5 boards using a 3.1 GHz Desktop
• 17 moves: 2.5s
• 25 moves: 32 minutes
• My memory utilization:
• < 4KB, independent of number of moves in solution

Evalulation Feedback

A1 Observations
• Elegance pays, C is fast: keep it simple
• Heuristics?
• Specification is trivial – inputs and outputs
• Design: don’t do elaborate documentation at first
• Sketch it on a napkin: most important for YOU to have a clear idea
• Document it properly as nearing completion to avoid rework.
• Code:

Evalulation Feedback

A2
• See handout on web site
• Work in teams of up to 3
• Do an automated regression testing environment for A1
• Use my code if you want
• Get your team together and do up a preliminary release plan
• Follow format of Deterministic Release Plan in Appendix A
• Decide on dates
• Estimate feature sizings and w’s
• Due next week in lecture
• Hand in at the last lecture:
• Release plan updated with actuals
• Your time logs
• System design and description
• Source code
• Experience report (< 1 page).
