I'm new to mining and I'm just wondering if there are other algo's that does a similar thing as Claymore. Like Claymore's competitor or proprietary algo that people use? Curious, common sense tells me that Claymore is not the only program that can write program. Thank you for enlightening me!
You might be a little confused here, or used wrong wording. Either way, a hashing algorithm is something that is used for Proof-of-Work. Claymore's miner is just that, a miner.
That said, it really depends on what GPU you're using and what coin you want to mine. I'd say it's reasonable to assume that Cast XMR for Vega GPUs is better than Claymore's XMR miner for example.
Do some research on the miners that are available for the GPUs you have/plan to use & coin you want to mine and you'll find the best miner yourself.
