Detailed Description

template<class UserNodeLabel, class UserEdgeLabel>
class ged::BranchTight< UserNodeLabel, UserEdgeLabel >

Computes lower and upper bounds for general edit costs.

Implements the method BranchTight suggested in:

D. B. Blumenthal and J. Gamper: “Improved lower bounds for graph edit distance”, https:://doi.org/10.1109/TKDE.2017.2772243

Supports the following options:

`--<option> <arg>`	modified parameter	default	more information
`--iterations <convertible to int greater equal 0>`	maximal number of iterations	`20`	https:://doi.org/10.1109/TKDE.2017.2772243 if `0`, no iteration based termination criterion is used
`--time-limit <convertible to double>`	time limit in seconds	`0`	https:://doi.org/10.1109/TKDE.2017.2772243 if less or equal `0`, no time limit is enforced
`--range <convertible to double>`	range	`0`	https:://doi.org/10.1109/TKDE.2017.2772243 if less or equal `0`, no range based termination criterion is used
`--epsilon <convertible to double>`	range	`0`	https:://doi.org/10.1109/TKDE.2017.2772243 if less or equal `0`, no convergence based termination criterion is used
`--regularize NAIVE\|K-FACTOR`	regularization method	`NAIVE`	https:://doi.org/10.1109/TKDE.2017.2772243
`--threads <convertible to int greater 0>`	number of threads	`1`	n.a.
`--upper-bound NO\|FIRST\|LAST\|BEST`	upper bound returned by the method	`BEST`	https:://doi.org/10.1109/TKDE.2017.2772243

	)

finalprivatevirtual

Parses one option.

Parameters

[in]	option	The name of the option.

	)

finalprivatevirtual

Runs the method with options specified by set_options().

Parameters

[in]	g	Input graph.
[in]	h	Input graph.
[out]	result	Result variable.
