From this:
the arrival of a new block has special significance for a mining node. The competition among miners effectively ends with the propagation of a new block that acts as an announcement of a winner. To miners, receiving a valid new block means someone else won the competition and they lost. However, the end of one round of a competition is also the beginning of the next round. The new block is not just a checkered flag, marking the end of the race; it is also the starting pistol in the race for the next block.
So I just wanted to clarify because I don't think I've seen it written down anywhere, that it's in a miners best interest to create their own algorithms to solve the computational challenges involved in mining. It's not as if every miner gets a standard algorithm and runs that. Please correct me if I'm wrong.
