A graph that shows the number of balls in and out of the vase for the first ten iterations of the problem. The Ross–Littlewood paradox (also known as the balls and vase problem or the ping pong ball problem) is a hypothetical problem in abstract mathematics and logic designed to illustrate the paradoxical, or at least non-intuitive, nature of infinity.
The ping-pong lemma was a key tool used by Jacques Tits in his 1972 paper [2] containing the proof of a famous result now known as the Tits alternative. The result states that a finitely generated linear group is either virtually solvable or contains a free subgroup of rank two.

Doing so omits the copy operation and reduces the total number of moves by half. An early public domain implementation of a four-at-once merge was by WikiSort in 2014, the method was later that year described as an optimization for patience sorting and named a ping-pong merge. [10] [11] Quadsort implemented the method in 2020 and named it a ...
In routing, a Ping-Pong scheme is a simple algorithm for distributing data packets across two paths. If you had two paths A and B, then the algorithm would randomly start with one of the paths and then switch back and forth between the two. [3]
Slam pong is a fast-moving variant of beer pong that retains some of the rules of table tennis and includes others from volleyball. The "slam" in slam pong refers to the action of slamming a table tennis ball with a paddle into a plastic cup of beer placed on the table, the fundamental way of scoring points in the game.
