#ThisWeeksFiddler @xaqwg.bsky.social: Anita the Ant To figure out what was going on, I made an animation. I found that Anita the Ant's path ended up inscribing a 2-3-2 isosceles triangle.

#ThisWeeksFiddler @xaqwg.bsky.social Here are the average lengths of the longest increasing subsequences of all the permutations of n elements. (The numerators in the table come from oeis.org/A003316.)

#ThisWeeksFiddler @xaqwg.bsky.social: This chart shows the probability of being able to achieve various dollar amounts of cash if you start with three $10 vouchers and one $25 voucher and play optimally for each amount.
Chart showing (dollar amount, probability): ($30, 100%), ($35, 100%), ($40, 87.5%), ($45, 81.641%), ($50, 76.562%), ($55, 68.75%), ($60, 68.75%), ($65, 59.375%), ($70, 59.375%), ($75, 50.781%), ($80, 50.195%), ($85, 50%), ($90, 50%), ($95, 43.75%), ($100, 40.82%), ($105, 38.281%), ($110, 34.375%), ($115, 34.375%), ($120, 29.688%), ($125, 29.688%), ($130, 25.391%), ($135, 25.098%), ($140, 25%), ($145, 25%), ($150, 21.875%)

#ThisWeeksFiddler @xaqwg.bsky.social I wrote code to emulate playing the game of bowling. I found 420,571 possible states in the game including 25,646 terminal states. With this list in hand, it was a matter of finding the terminal states that best qualified in each case.

#ThisWeeksFiddler @xaqwg.bsky.social How many different equilateral triangles in the game of Dozo? I found 11 different sizes of triangle. The smallest appeared at 36 different locations and orientations on the Dozo board. The largest appeared just once.

#ThisWeeksFiddler @xaqwg.bsky.social EEC: There is a faint message scrawled onto the second scroll which you can barely make out: "Nullus numerus repetitur", i.e., "No number is repeated". How many combinations are possible if none of the eight numerical inputs is used more than once?

#ThisWeeksFiddler @xaqwg.bsky.social Here is "a" solution to the extra credit. Very likely not "the" solution because I could only approximately calculate the volume remaining and couldn't figure out a way to find the greediest cylinder at each step. I obliterated the sphere in 12 steps. YMMV.

#ThisWeeksFiddler @xaqwg.bsky.social Extra credit: How many distinct paths are there from the top of a triangular bipyramid to the bottom, if (1) you never visit the same point twice and (2) you move only downward or sideways? Short answer: A lot, especially with larger bipyramids.

#ThisWeeksFiddler @xaqwg.bsky.social This chart shows how the likelihood of each series result depends on the probability p of the Celtics winning an individual game. The likelihood of "Celtics in 5" (blue line) is greater than the likelihood of any other result when p is between 0.6 and 0.75.

#ThisWeeksFidder @xaqwg.bsky.social The largest gaps seem to lie on either side of the nearest trees. The nearest tree is at (2,1) and it separates the 2 largest gaps. The next nearest trees are at (3,1), (3,2), (4,1), and (4,3). The illustration shows gaps when visibility is 100.

#ThisWeeksFiddler 28 Mar 2025 I tried running the tournament with different boost values, namely 0.5, 1.5, 2.5, and 3.5. Every team won except for the team with power index 3.
