What is recorded here?
Placed heuristic graph search in a formal minimum-cost framework and analysed conditions under which the A* class returns minimum-cost paths.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The 1968 paper’s stronger optimality claim was corrected in 1972. This entry retains the admissibility/minimum-cost contribution without repeating the unqualified original theorem.
