Claim One:
1. A method for positioning plural electromagnetic sensors in an array, the method comprising the steps of: (1) designating one of the plural sensors as a reference sensor relative to a reference system, wherein the reference sensor is one of two of the plural sensors that are a greatest distance apart from each other; (2) calculating a first vector of components according to: ##EQU6## (3) calculating a second vector of components: ##EQU7## where i is the index associated with an i order sensor; X.sub.i, Y.sub.i are coordinates of the i order sensor along an X-axis and a Y-axis, respectively, of the reference system; X.sub.i+1, Y.sub.i+1 are coordinates of an i+1 order sensor along the X-axis and the Y-axis, respectively, of the reference system; D is a distance between the two sensors of the plural sensors that are the greatest distance apart; (4) applying a genetic algorithm to the first and second vectors, .DELTA..sub.i and d.sub.i, respectively, to obtain x and y positions of the plural sensors in the array (5) positioning plural electromagnetic sensors in the array in accordance with the genetically encoded x and y positions pattern of the plural sensors.
