What are the algorithms for calculating the recommended price?

Question

Algorithms

Tell me, the algorithms for calculating the recommended price for a product, based on sales statistics: (time of sale, price, quantity) every hour.
What methods exist, what literature would you recommend?
Thanks in advance for your replies!
For example, the BlablaCar service indicates the recommended price for a trip, how does it do it?

Answer 1

the "Russian" algorithm: we set it from the bulldozer, we take it - we increase it, we don't take it - we reduce
it, and so - this is the usual terry economy
PS after the comment about blablacar I will add - the algorithm works fine in Uber: during weekdays rush hour on weekends (when traffic jams 1-3 points): after several requests within 15-30 minutes
, it decreases from one and a half to normal
