Comments from John Hamer

• Why did you choose 1000 as the sample size? You were asked to give a justification for your choice.

• The llps data is for the second experiment. Don't include it with the data for the first one.

• Why choose a table size of 10,000 when you are only inserting 1,000 keys? This is a ridiculously low load factor

• Java String Hash typical gave a llps of 999. Didn't you find that odd?

• Java Integer Hash low gave a llps of 1. Didn't you find that odd?

• Java Integer Hash typical gave a llps of 91. Didn't you find that odd?

• Java Object Hash low gave a llps of 1000. Didn't you find that odd?

• Your ANALYSIS table is great, but why omit the other randomness test results? Entropy is good, but SCC is pretty much useless at discriminating.

You have given plenty of results, but little or no analysis. There were lots of interesting things that you missed, giving the impression that you have not actually looked at the data at all. These numbers mean something, and you need to think about what that is. You have not reflected on the lab as asked. What did you find difficult? What didn't you understand?

A weak effort.

Note

I had not finished the lab after spending about 3 hours on it so I left it to come back to hence the lack of analysis.
