Think you’ve mastered quadratic equations? Think again! This insanely tricky problem will put your algebra skills to the ...

Abstract: An iterative algorithm to solve Algebraic Riccati Equations with an indefinite quadratic term is proposed. The global convergence and local quadratic rate of convergence of the algorithm are ...

Abstract: We develop a numerically efficient algorithm for computing controls for nonlinear systems that minimize a quadratic performance measure. We formulate the optimal control problem in ...

Before algebra had letters, someone carved the first equation into wet clay. And yes they solved it faster than most of us could today. Long before algebra had a name, someone in ancient Mesopotamia ...
