I have an optimization problem and I am looking for a method rather than a solution here. I'll state it in a general form.
Let there be two functions: [itex]f_1(x_1,\cdots, x_n,y_1,\cdots, y_n )[/itex] and [itex]f_2(x_1,\cdots x_n,y_1,\cdots, y_n )[/itex].
Maximize [itex]f_1[/itex] with regards to variables [itex]x_1,\cdots, x_n[/itex] with [itex]y_1,\cdots, y_n[/itex] fixed at the values that maximizes [itex]f_2[/itex].
Maximize [itex]f_2[/itex] with regards to variables [itex]y_1,\cdots, y_n[/itex] with [itex]x_1,\cdots, x_n[/itex] fixed at the values that maximizes [itex]f_1[/itex].
You could regard them as two utility functions in a game theoretical problem where where agent 1 controls [itex]x_1,\cdots, x_n[/itex], and agent 2 controls [itex]y_1,\cdots, y_n[/itex]. Both utility functions depends on the choices of both players.
Any ideas of how to solve this? Thanks!
