spottedgeck.bsky.social @spottedgeck.bsky.social · 26/08/2025For #thisweeksfiddler, we race among randomly selected loops of length 1, 3, 3.5, 4.5 miles at a 10 min/mi pace. If unfinished loops don't count and we have 65 min left to race, how can we maximize the avg total distance completed? 010
spottedgeck.bsky.social @spottedgeck.bsky.social · 19/08/2025For #thisweeksfiddler by @xaqwg.bsky.social , we start with a set of vouchers ($10, $10, $10, $25), and can bet any of them on either side of an even odds game. 010

spottedgeck.bsky.social @spottedgeck.bsky.social · 16/06/2025For @xaqwg.bsky.social 's #thisweeksfiddler, we're in a race where we increase our speed continuously to the end. (1+b)v(2x) = v(x), where x is the distance remaining in the race and b is the factor we increase our speed. 111
spottedgeck.bsky.social @spottedgeck.bsky.social · 03/06/2025I reasoned that for two random points to be collinear to a given position, they must be on the same line oriented at angle theta away. The probability this happens is proportional to the length of the line segment contained within the square oriented at that theta. Then avg over all theta. 000

spottedgeck.bsky.social @spottedgeck.bsky.social · 19/05/2025For the EC, there are multiple points A from which we can reach point B in a given layer, and we must sum over the product of ways from A to B and the number of ways to reach point A. This number blows up quickly to over 1 billion. 000
spottedgeck.bsky.social @spottedgeck.bsky.social · 19/05/2025For the regular fiddler, there is only one way to travel from points A to B within one layer, therefore the number of ways to reach each point in a given layer is identical and equal to the sum of ways to reach all points A in the current layer. 100
