Class: least_used_strategy - X-Ref
A {@link \question_variant_selection_strategy} that randomly selects variants that were not used yet.If all variants have been used at least once in the set of usages under
consideration, then then it picks one of the least often used.
Within one particular use of this class, each seed will always select the
same variant. This is so that shared datasets work in calculated questions,
and similar features in question types like varnumeric and STACK.
| __construct(\question_usage_by_activity $quba, \qubaid_condition $qubaids) X-Ref |
| Constructor. param: question_usage_by_activity $quba the question usage we will be picking variants for. param: qubaid_condition $qubaids ids of the usages to consider when counting previous uses of each variant. |
