Conjugate Direction Methods for Quadratic Problems,tion. Consider the problem of finding . ∈ . satisfying ., where . ∈ ., . ∈ . and . is symmetric positive definite. The solution to this problem is also a solution of the optimization problem (.): .. Consider the point x̄ such that .. We can show that (1.2) are the necessary optimality conditions for problem (1.1).

agenda

Conjugate Gradient Methods for Nonconvex Problems,us chapter a conjugate gradient algorithm is an iterative process which requires at each iteration the current gradient and the previous direction. The simple scheme for calculating the current direction was easy to extend to a nonquadratic problem ..
