Algorithm engineer is a profession, which has nothing to do with her boyfriend's profession. So we can't simply say whether algorithm engineer's boyfriend is good or not, it depends on personal circumstances.

Algorithm engineer is a professional engaged in algorithm design, development, implementation, testing and optimization. They need to have a solid computer science foundation, algorithm design ability, programming ability and other skills. As professionals, they may encounter various challenges and pressures in their work, and they need to have strong work ability and professional ethics.

But as a boyfriend, his personal qualities, personality and behavior are more important. Algorithm engineer's identity is only a part of his career, not his life as a boyfriend. So you need to consider his personal qualities, mutual understanding, communication and support, and whether he is suitable to be your boyfriend.
