I was aware of the Boston Dynamics robots, but it always seemed to me that they move very slowly compared to walking/running humans. I suppose that may just be a precaution on their part, the jumping and gymnastics are certainly impressive otherwise.
Boston Dynamics use control-systems style robotic control. This is different to ML-style control where the system learns to perform tasks.
But that's different to "pre-programmed sequence". They don't program the individual servo movements for each movement - instead they give it the motions to perform and the control-systems balance the robot automatically.
(This is what the OP implied by the word "algorithms" anyway right?)
