Member Data Documentation

◆ absoluteErrorTol

double gtsam::NonlinearOptimizerParams::absoluteErrorTol = 1e-5

The maximum absolute error decrease to stop iterating (default 1e-5)

Definition at line 44 of file NonlinearOptimizerParams.h.

◆ errorTol

double gtsam::NonlinearOptimizerParams::errorTol = 0.0

The maximum total error to stop iterating (default 0.0)

Definition at line 45 of file NonlinearOptimizerParams.h.

◆ iterationHook

IterationHook gtsam::NonlinearOptimizerParams::iterationHook

Optional user-provided iteration hook to be called after each optimization iteration (Default: none). Note that IterationHook is defined as a std::function<> with this signature:

void(size_t iteration, double errorBefore, double errorAfter)

which allows binding by means of a reference to a regular function:

void foo(size_t iteration, double errorBefore, double errorAfter);
// ...
lmOpts.iterationHook = &foo;

or to a C++11 lambda (preferred if you need to capture additional context variables, such that the optimizer object itself, the factor graph, etc.):

lmOpts.iterationHook = [&](size_t iter, double oldError, double newError)
{
// ...
};

or to the result of a properly-formed std::bind call.

Definition at line 95 of file NonlinearOptimizerParams.h.
