Games have long served as a benchmark for progress in the field of AI. Another interesting observation was that one of the important steps was to come up with a new formalism, allowing for truly general design of search based algorithm.' 'One takeaway is that one can indeed design a technique that can work for both perfect and imperfect information games, rather than having specialized algorithms. 'This is a step towards making even more general algorithms,' study lead author Martin Schmid, CEO and co-founder of EquiLibre Technologies, told Live Science in an email.
