This paper proposes a novel general framework of Riemannian conjugate gradient methods, that is, methods on manifolds. The are important first-order optimization algorithms both in Euclidean spaces and While various types studied spaces, there have been fewer studies those In each iteration the previous search direction must be transported to current tangent space so it can added negative objec...

Food preparation methods applied to African traditional vegetables vary greatly depending on preferences of various consumers. Vegetable amaranth is one the most preferred vegetable, with high nutritional quality.
