“…There is substantial literature on this class of problem (details can be found in the following references: [9], [12] and [20]). Other results were published on differential game with integral constraint (see [2], [3], [7], [8], [9], [10], [12], [13], [14] [15], [16], [17], [18] and [20]). In some of these research works, players dynamics are described by ordinary differential equations.…”
