A '''Bongard problem''' is a kind of puzzle invented by the Soviet [[computer scientist]] [[Mikhail Bongard]] (1924–1971), probably in the mid-1960s. They were published in his 1967 book on [[pattern recognition]]. The objective is to spot the differences between the two sides. Bongard, in the introduction of the book (which deals with a number of topics including [[perceptron]]s) credits the ideas in it to a group including M. N. Vaintsvaig, V. V. Maksimov, and M. S. Smirnov.
