Member Function Documentation

add_bin()

Bin_index add_bin ( Bin_energy_range  bin )

inlineprotectedinherited

add_bin is a helper function which add a bin to the bin vector/ properties vector

Parameters

bin

Returns

energy_out_of_range()

std::pair<bool,Snapshot_ptr> energy_out_of_range ( const DS_conformation &  conf )

inlineinherited

energy_out_of_range is called when a point is sampled in a not already existing bin. It should handle the creation of a new bin if supported. This should be modified to initialize Custom_per_bin_stats at propers values if needed.

Parameters

conf

Returns

false is returned if this case is not supported. WL algorithm should then quit gracefully.

get_bin_index_from_energy() [1/2]

Bin_index get_bin_index_from_energy ( const double &  e )

inlineinherited

get_bin_index_from_energy finds the bin containing the energy e

Parameters

e

Returns

return a Bin_index describing the bin contatining energy e. If no bin contains e, an invalid bin is returned (here -1)

get_bin_index_from_energy() [2/2]

Bin_index get_bin_index_from_energy ( const double &  e, const double &  e1, const Bin_index &  i1  )

inlineinherited

get_bin_index_from_energy should uses that the point previously sampled should be in a bin close to the new newly sampled point

Parameters

e	new energy
e1	previous energy
i1	previous bin

Returns

get_density()

double& get_density ( const Bin_index &  index )

inlineinherited

get_density returns the density of a point

Parameters

index

Returns

is_energy_in_range()

bool is_energy_in_range ( const DS_conformation &  conf )

inlineinherited

is_energy_in_range checks if a Bin_index is valid.

Parameters

conf

Returns

update_densities()

void update_densities ( const Bin_index &  index )

inlineinherited

update_densities updates the density vector when a new point is sampled by the WL algorithm.

Parameters

index

update_histogram()

void update_histogram ( const DS_conformation &  newpt, const DS_conformation &  oldpt, const bool &  accepted, const bool &  boundary_check  )

inlineinherited

update_histogram is called when a new point is sampled. It should be used to store some statistics on how the algorithm is working, which might be later used in update_parameters()

Parameters

oldpt	previous point in the algorithm
newpt	point sampled by the Point_generator
accepted	is the new point accepted after the metropolis test
boundary_check	is the result of the boundary check

update_increment()

virtual Snapshot_ptr update_increment ( )

inlinevirtualinherited

update_increment is called after new points have been generated and accepted(or not) in the WL algo. it updates the increment by which the (log) density is increased when a new point is generated in a given bin.
