Abstract
Adaptive raising by successive trials t 0 < t 1 < ... until some unknown goal g > 1 has been found by t n ≥ g, causingtotal cost T(g) = t 0+...+t n, is studied for optimizing T(g)/g. For corregames, where player G setting g and ‘finder’ F choosing t 0, t 1, . . . are playing mixed strategies, we prove a “Law of optimal adapting factor e”. Section 2 is more general about adaptive raising on several tracks, in Sect. 3 we add proofs for the optimal competitive factors under corresponding worst case analysis.— Methods and results are similar to those about searching for a point on a line or on many rays, see [[1], [3], [4], [5], [6]].
