An alternative in the differential-difference game of approach — evasion with a functional target : PMM vol. 40, n 6, 1976, pp.987–994

An approach-evasion problem with a functional target set under constraints on the system's trajectory is studied for a conflict-con trolled system described by a differential-difference equation. The main result states: either a strategy exists for the first player resolving the approach problem or a strategy exists for the second player resolving the evasion problem.
