Function Documentation

def gtsam.utils.logging_optimizer.gtsam_optimize	(		optimizer,
			params,
			hook
	)

Given an optimizer and params, iterate until convergence.
    After each iteration, hook(optimizer) is called.
    After the function, use values and errors to get the result.
    Arguments:
            optimizer {NonlinearOptimizer} -- Nonlinear optimizer
            params {NonlinearOptimizarParams} -- Nonlinear optimizer parameters
            hook -- hook function to record the error

def gtsam.utils.logging_optimizer.optimize	(		optimizer,
			check_convergence,
			hook
	)

Given an optimizer and a convergence check, iterate until convergence.
    After each iteration, hook(optimizer, error) is called.
    After the function, use values and errors to get the result.
    Arguments:
        optimizer (T): needs an iterate and an error function.
        check_convergence: T * float * float -> bool
        hook -- hook function to record the error
