i'm not asking code random number algorithm is, believe prng, psuedorandom number generator: how random number algorithm generator code, use same class structure concrete class in java instance variables, default constructors, overload constructors, getmethods, methods, tostring, or code these algorithms different way? in addition, wondering if there specific programs 1 use create algorithm class? note: if have question, fell free leave them in comments before downvoting question. thank can appreciated! note: also, know there lot of algorithms out there, when looking answer, if end needing answer. great if java algorithms or common type of algorithms in general, not random ones. again!

i think variant of classic 0/1 knapsack problem. say, assume plan steal treasure given capacity limit(say 2v). given capacity limit, have 2 choices: 1 bag capacity 2v, or 2 bags capacity v sepetately. there mathmatical formula can use pre-compute solution better(give better optimal value)? or have compute optimal value seperately via different recurrence regulation , choose better one? more over, can generalize problem one: given capacity limit(v), can take 1 bag capcity v or take k bags capcity v/k conduct stealing. , eonchoose best 1 solve problem one bag better. content of n bags solution can fit 1 bag, not vice versa.

consider table named books table books has attributes: isbn booktitle author_num lastname publisher royalty edition the primary keys bolded there partial dependencies isbn can determine booktitle isbn can determine edition author_num can determine last name there transitive dependency: - booktitle can determine publisher what best way , systematic way normalise table? for me, is: identify non-primary key holds partial dependency , no transitive dependency (i.e. isbn can determine booktitle , edition using rule , author_num can determine lastname) , put them in separate table each instance of rule applies partial dependencies allow transitive dependency occur grouped in own table (i.e. booktitle & publisher) final table have values associated 2 initial determiners of partial dependency (isbn, author_num values hold no dependency i.e. royalty) diagram:
