Playing with lagrangian mechanics

The principle of least action states that the path followed in time by a physical system subject to conservative forces is such to minimize (or, more generally, make stationary) the action , where the lagrangian is the difference between kinetic … Continue reading

Constrained optimization without lagrangian multipliers

There is an obvious alternative to using lagrangian multipliers for constrained optimization: reformulate the problem in the subspace of constraints and it becomes automatically a non constrained problem. It is not always obvious, though, how one can do so in … Continue reading
