Determination of optimum location for drilling a new well not only requires engineering judgments but also consumes excessive computational time. Additionally, availability of many physical constraints such as the well length, trajectory, and completion type and the numerous affecting parameters including, well type, well numbers, well-control variables prompt that the optimization approaches b...

This paper addresses the optimization of pseudo-random planar point patterns for invariant-based identiication or indexing. This is a novel problem and is formulated here as the maximization of the spacing of all the invariants when considered as points in a space. The task is of formidable complexity and a stochastic approximation strategy is proposed that yields interesting results.
