setVariableActivityDecay

public SatParameters.Builder setVariableActivityDecay(double value)

 Each time a conflict is found, the activities of some variables are
 increased by one. Then, the activity of all variables are multiplied by
 variable_activity_decay.

 To implement this efficiently, the activity of all the variables is not
 decayed at each conflict. Instead, the activity increment is multiplied by
 1 / decay. When an activity reach max_variable_activity_value, all the
 activity are multiplied by 1 / max_variable_activity_value.

Parameters:: value - The variableActivityDecay to set.
Returns:: This builder for chaining.

hasAbsoluteGapLimit

public boolean hasAbsoluteGapLimit()

 Stop the search when the gap between the best feasible objective (O) and

 Important: The relative gap depends on the objective offset! If you
 artificially shift the objective, you will get widely different value of
 the relative gap.

 Note that if the gap is reached, the search status will be OPTIMAL. But
 one can check the best objective bound to see the actual gap.

 If the objective is integer, then any absolute gap < 1 will lead to a true
 optimal. If the objective is floating point, a gap of zero make little
 sense so is is why we use a non-zero default value. At the end of the
 search, we will display a warning if OPTIMAL is reported yet the gap is

getSubsolversList

public com.google.protobuf.ProtocolStringList getSubsolversList()

 In multi-thread, the solver can be mainly seen as a portfolio of solvers
 with different parameters. This field indicates the names of the parameters
 that are used in multithread.

 See cp_model_search.cc to see a list of the names and the default value (if
 left empty) that looks like:
 - default_lp           (linearization_level:1)
 - fixed                (only if fixed search specified or scheduling)
 - no_lp                (linearization_level:0)
 - max_lp               (linearization_level:2)
 - pseudo_costs         (only if objective, change search heuristic)
 - reduced_costs        (only if objective, change search heuristic)
 - quick_restart        (kind of probing)
 - quick_restart_no_lp  (kind of probing with linearization_level:0)
 - lb_tree_search       (to improve lower bound, MIP like tree search)
 - probing              (continuous probing and shaving)

 Also, note that some set of parameters will be ignored if they do not make
 sense. For instance if there is no objective, pseudo_cost or reduced_cost
 search will be ignored. Core based search will only work if the objective
 has many terms. If there is no fixed strategy fixed will be ignored. And so
 on.

 The order is important, as only the first usable "num_workers -
 min_num_lns_workers" subsolvers will be scheduled. You can see in the log
 which one are selected for a given run. All the others will be LNS if there
 is an objective, or randomized SAT search for pure satisfiability problems.

 - lb_tree_search       (to improve lower bound, MIP like tree search)
 - probing              (continuous probing and shaving)

 Also, note that some set of parameters will be ignored if they do not make
 sense. For instance if there is no objective, pseudo_cost or reduced_cost
 search will be ignored. Core based search will only work if the objective
 has many terms. If there is no fixed strategy fixed will be ignored. And so
 on.

 The order is important, as only the first usable "num_workers -
 min_num_lns_workers" subsolvers will be scheduled. You can see in the log
 which one are selected for a given run. All the others will be LNS if there
 is an objective, or randomized SAT search for pure satisfiability problems.
