Solver specification

The solver specification defines its type and parameters. For now, WOLF only has the SolverCeres solver, located in the plugin core. If the user is not familiar with Ceres, it is recommended to use the configuration used in the provided demos, which are already tuned for most problems.

Note

Remember that the YAML templates contains all the parameters of each class and a brief doc. You can start from the templates and modify them to suit your needs. See more information in the YAML schema section.

The following is the part of the WOLF ROS2 application example configuration file, containing the solver specification.

solver:
  follow: "solver.yaml"

Note that the parameters are contained in another file to be reused in other applications.
