  1. Moving South and East

    I saw this riddle before, and I implemented an HTML version of it: http://anzapower.webs.com/riddles/amoeba/game.html And actually it has already been posted:
  2. 5 Language Equations

  3. Ken Ken 3

    Question, can the digits repeat inside an L-shaped area? For example the 14+ be: 2 6 6 ??
  4. brain puzzle

    Or dump everything and have 0 in all of them
  5. dice problem

    Actually it's O(1). Your comment got me thinking, I couldn't say that it's in NP because there is no n in the problem, We have 130 as a starting point and we want to see if any of the binome(129,8) dice combinations have 120 different sum... Unless you are referring to the problem with "N-sided Dice", then yeah that's crazy exponential...
  6. A boy is late for school

    Is the arrival time continuous or discrete (whole minutes)? Can we assume the distribution is uniform? Continuous time is the interesting case so let's look at that with uniform distribution:
  7. [0,1] to (0,1)

  8. Question is why would I go around pushing cubes in holes that are in other cubes?
  9. building a bridge

    You might've misunderstood me a little bit, I should have detailed a bit more, let the river be of width 1 unit, align the axis such that the x axis is parallel with and centered the river, in other words the river would be the area -0.5<y<0.5, now "removing" the river means collapsing it and so every point that was below it now goes up by 0.5 units and every point above it goes doen 0.5 units...
  10. [0,1] to (0,1)

    No other conditions, although if you want something really interesting try having a continuous function...
  11. Sharing a sandwhich

    You mean show that for any shape there exists a direction such that if you slice through it you get two equal halves?
  12. [0,1] to (0,1)

    Find a one-to-one and on mapping from the closed segment [0,1] to the open segment (0,1).
