The writers Cesare Pavese and Natalia Ginzburg thought it too early after the war for such an account. Levi managed to find a smaller publisher, De Silva, who printed 2,500 copies of the book, 1,500 of which were sold, mostly in Levi's hometown of Turin. In 1955, Levi signed a contract with Einaudi for a new edition, which was published in 1958. The initial printing of 2000 copies was followed by a second of the same size. An English translation
Distance geometry problem length of the straight-line path from "A" to "C" plus the length of the straight-line path from "C" to "B". This fact is called the triangle inequality. If that sum happens to be "equal" to the distance from "A" to "B", then the three points "A", "B", and "C" lie on a straight line, with "C" between "A" and "B". Similarly, suppose one knows Knowing only these six numbers, one would like to figure out Distance geometry includes the solution of such problems. Of particular utility and importance are classifications by means of Cayley–Menger determinants, named after Arthur Cayley and
