Happy Birthday, Stephen Cook! May your celebrations be polynomial-time solvable and free from NP-complete complexity. Your groundbreaking contributions to computational theory have left us all scratching our heads—but in the best possible way!From pioneering work on complexity theory to unraveling proof complexities, you've shown that life's toughest problems can indeed be elegantly framed (even if not always easily solved). Here's hoping this birthday brings you joy that's exponentially greater than any algorithm could predict.
Cheers to another year of brilliant insights—and may your cake-cutting problem remain delightfully simple today. Happy Birthday!
