Understanding Bilevel Optimization

Bilevel optimization is a branch of mathematical programmming where one optimization problemm (thate upper lear level) prestizatioon masalah (the lower lear) adalah sebuah kendala.

Formally, sebuah standard bilevel problemm can be expressed as:

Upper level: minimize F (x, y) subjett to G (x, y) 0y the optimal solution of the lowerl problemm: minimize f (x, y) subjitt to g (x, y) psydom0.

Here, x represents upperterts variables (e.g, paragic target or paradir), and y denotes lower- level variables (e.g, operasiali settitik).
