Conway Look-and-say Sequence
Let’s play a game with integer sequences. Observe the following sequence: [\begin{align} 1 11 21 1211 111221 312211 \vdots \end{align}] Can you tell the next number? ...

Motivation Recently, I came across an interesting application of the Lovász Local Lemma, a fundamental technique in the “probabilistic method” and a classic example of a non-constructive approach i...
