The description of a series of attempts to solve the conceptually difficult Firing Squad Synchronization Problem. These attempts demonstrate an increasing reliance on man-machine symbiosis and a decreasing reliance on powerful heuristics and preplanning. This problem arises in connection with causing all parts of a self-producing machine to be turned on simultaneously. Each of the four attempts described has in common a clerical checking program and a basic backtracking program for searching the solution space. The first two attempts at solution are noninteractive and entirely computer directed. The second two attempts are man-machine symbiotic; they are designed to allow the human to control and direct the computer search of the solution space. Recommendations are made concerning factors for consideration in man-machine symbiosis and the production of working interactive systems. 32 pp. Ref.
