Complex of programs was created, approximating the three-dimensional anomalies of the magnetic induction modulus (ATa) for singular sources class (P) - the uniformly magnetized segments. At the present time the algorithm for direct search of Hooke - Jeeves was chosen to solve the nonlinear programming tasks. Programs were tested on theoretical examples and acceptable results were achieved. The quantitative interpretation of the magnetic anomalies was made for the Bronze Age archaeological settlement Konopljanka.
