Abstract:
A method for arranging a plurality of dimples on a golf ball, comprising the steps of:initially distributing the plurality of dimples on a surface of a computer golf ball model,selecting one dimple and performing on the one dimple at least one alteration selected from movement and rotation of the one dimple and geometrical enlargement or contraction of dimples such that the sum of the squares of boundary spherical distances between the one dimple and adjacent dimples may be minimum and the dimples do not overlap each other,iterating the alteration on the remaining dimples, andterminating the alteration operation when the value of Sk is smaller than a desired convergence criterion value, said Sk being given by the equation: ##EQU4##wherein i, j and k are counters, Sk is the sum of the squares of distances between adjacent dimples, calculated for all the dimples, 1 is added to k whenever optimization is performed on all the dimples, N is the total number of dimples, Mi is the number of dimples adjoining an i-th dimple, and Lij is the distance between an i-th dimple and a j-th dimple among a Mi number of dimples adjoining the i-th dimple, the dimple distribution thus obtained providing a dimple arrangement on the golf ball.
