Improved Minimum Curvature Iteration Algorithm for Intrapolation and Extrapolation of Gravity Profile Data
Abstract We discover a new minimum curvature algorithm, based on the idea that the constraints are treated as unknown sites. The improved method avoids complicated reduction, without the need to consider the relationship between constraint points and unknown points when the constraint points exist around the unknown points. Furthermore, precision is improved.
