Webb4 feb. 2024 · The problem of finding the best lower bound: is called the dual problem associated with the Lagrangian defined above. It optimal value is the dual optimal value. As noted above, is concave. This means that the dual problem, which involves the maximization of with sign constraints on the variables, is a convex optimization problem. WebbOur problem solving pages provide a simple and structured approach to problem solving. The approach referred to is generally designed for problem solving in an organisation or group context, but can also be easily adapted to work at an individual level at home or in education.
