So, for the past week I've been in Vegas, residing at the Aladdin Resort, located right in the middle of the strip. People were there. Fun things were done! Poker was played with Ruberik and Dethridge to name a couple. Astronomy was discussed with Reid and Rustyoldman to name a couple. The roller coaster around New York New York got ridden twice.

My team only finished 6th place at the NWERC, so I guess I won't be seeing those of you whom I would be seeing in Texas in Texas anyway. Oh, well. We can always try again next year, provided I continue to to grad studies. Is doing programming contests a good reason to study? I guess ( Read more... )

"Bird perched on Pallas
Is Lenore now in Aidenn?"
Quoth the raven, "no"

Tomorrow I'm going to Stockholm for the ACM NWERC. Eep!

Edit:
Hmm.. shouldn't the first line in a poem be about something fleeting? I fear that mentioning Pallas kind of disrupts that. I'm not sure what would be a good rewriting, though.

So the programming contest yesterday went pretty well ( Read more... )

1. This and this made me quite depressed the last week. But LiveJournal isn't a place to lament about what makes you sad, so we move on ( Read more... )

How to solve exponential-time problems in linear time
or
Why Kalmakka should not be allowed to discuss complexity theory (esp. with _dw)

Say you have an algorithm that takes O(kn) time for some k. Wait O(n) time for Moore's law to build up, build a computer kn times as fast as those of today and solve the problem in O(1) time. Total time = O(n) + O( ( Read more... )

On-input test: Input must consist of only plus, minus, digits and decimal separators
On-submission test: Input must be a valid floating point number with a decimal separatorIssue: In the first case, a 'decimal separator' is equivalent to a period. In the second case a 'decimal separator' is locale dependent, i.e. a comma in Norway ( Read more... )

The following relationship must also hold:

0 <= first_is <= max_is

The following relationship must hold when max_is <= 0:

first_is == 0

Does the word 'tautology' come to mind?
Really! That's the least informative thing I've heard all week!

So, the main() function is unnecessary. Now, the big question becomes "how complex programs can you create without defining functions at all?" (If you've taken concurrent programming at Waterloo, you'd learn that arbitrary restrictions like this is known as "structured programming", although in my opinion, "constrained programming" would be a ( Read more... )
