Instance Method Details

#entity_types ⇒ Object

this includes workers and entities, and actually anything that could be needed for the cycle.

field :entity_types, type: Hash, default: {}

#find_applicable_minute(cycle_requirements_array) ⇒ Object

match where [cycle is a and cycle is primary] OR [cycle is b and cycle is primary, cycle is c and cycle is primary] present. then unwind the cycles so now we know that all these cycles even if they don’t be primary, still belong to a minute with a primary now match only the useful cycles group by minutes add a field that combines the size of the avialable cycles + the distance from now sort by that. @param cycle_requirements_array : , worker_requirements :{“type” : number, entity_requirements: : number} @param transport_information : : , coordinates : lets get the edit out of the way first.

next step is to pull correctly. so this done.
