Use this optimization step or heuristic to study an explicitly defined objective and constraints with reproducible parameters, initialization, and stopping rules.

position

Required list input.

gradient

Required list input.

previous Gradient

Required list input.

previous Direction

Required list input.

learning Rate

Required number input.

Compute a Fletcher–Reeves conjugate-gradient direction and one caller-sized step from current and previous gradients. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Next position

The resulting next position returned as a list.

Direction

The resulting direction returned as a list.

Fletcher–Reeves beta

The resulting fletcher–reeves beta returned as a number.

• Convergence and solution quality depend on smoothness, convexity, scaling, gradients, conditioning, hyperparameters, randomness, constraints, and implementation details. Non-convex methods need not find a global optimum.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Scale variables, monitor objective and constraint residuals, compare starts and algorithms, and verify small instances or local optimality with an independent solver.

• Gradient Descent Optimizer Step

  Apply one gradient-descent update x − η∇f; the caller supplies the gradient and learning rate.

• L-BFGS Optimizer Step

  Compute one limited-memory BFGS two-loop direction from valid curvature-pair histories and apply a caller-supplied step size.

• Adagrad Optimizer Step Calculator

  Calculate one scalar Adagrad parameter update and its accumulated gradient state.
