A powerful technique called SAT solving could work on the notorious Collatz conjecture. But it’s a long shot. But Heule, a computer scientist at Carnegie Mellon University, has set his sights on an ...

At first glance, the problem seems ridiculously simple. And yet experts have been searching for a solution in vain for decades. According to mathematician Jeffrey Lagarias, number theorist Shizuo ...
