i want implement roulette wheel selection in ga algorithm. tried following guide https://stackoverflow.com/a/5315710/536474 sends new population instead of 2 best parents. suppose found fitness score initial population , need select 2 parent chromosomes population according fitness. , further goes crossover , mutation processes. in following case, how can find 2 best parents crossover based on roulette wheel selection? population = [[text1],[text2],[text3],.....[textnum]] fitnesses = [0.8057515980834005, 1.2151126619653638, 0.6429369518995411, ... 0.805412427797966] num = 50 it doesn't send new population, num parents. if want 2 parents call roulette_select way: roulette_select(population, fitnesses, 2) often ga crossover operator expects 2 parents there variations many parents (e.g. genetic algorithms multi-parent recombination - a.e. eiben, p-e. raué, zs. ruttkay ). there self-crossover operators. so having num input parameters makes sense.

i'm working through exercises in the swift programming language , , 1 thing noted odd array syntax. per this answer , array<t.generator.element>() works, yet var common = [t.generator.element]() not. @ same time, var common: [t.generator.element] = [] correct. what rules around array syntax/initialization? why doesn't second line work?

when using <video> tag alone, 1 adds crossorigin attribute so: <video src="blah" crossorigin="anonymous"></video> however, i've had trouble finding out correct placement of 'crossorigin' when using multiple video sources , example: <video> <source src="/somesource.mp4"> <source src="/somesource.webm"> </video> do put 'crossorigin' attribute on <video> tag or individual <source> tags? if later, mean each source can have individual crossorigin handling within 1 video tag? do put 'crossorigin' attribute on tag or individual tags? the w3c specs specify crossorigin attribute on video tag (or more precisely htmlmediaelement) not on src element (or again more precisely, htmlsourceelement). so, assuming follows specs, rash assumption - see margus's answer exmple, should put cross origin attribute on video tag rather individual source ...

i know tcp has 16-bit checksum, catch errors in transmission. tcp outputs on other end theoretically reliable... point. this article suggests tcp not reliable 1 might hope if after "high reliability": http://iang.org/ssl/reliable_connections_are_not.html#ref_6 are there readily available protocols, or transport libraries (c/c++ preferred), more reliable tcp? speed of moderate concern too. i imagine transport library reimplementation of of parts of tcp. it shame tcp isn't more flexible allow tradeoff more reliability @ cost of throughput/latency/speed. lot more reliability if made checksum 32-bit instead of 16-bit. , again if chose make 64-bit. there seems big cost adding own reliable transport layer on top of tcp: starters, hardware acceleration support processing tcp won't suffice, , you'll need provide of cpu time process layer. additionally, lot of complexity , code implement such thing, have been avoided if tcp checksum larger or selectable. ...

i have graph this: and implemented graph array this: g[i][j][k] k has 4 cells , shows whether vertex connected 4 neighbor vertices or not. example for: g[1][1][0] = 0 g[1][1][1] = 1 g[1][1][2] = 1 g[1][1][3] = 0 it shows vertex(1, 1) connected 2 vertices. i know floyd warshall algorithm normal types of graphs. but how can implement flyod warshall algorithm kind of graph? thank. floyd-warshall algorithm inefficient such sparse graph. graph sparse because every vertex connected no more 4 other vertices. in dense graph vertex can connected n-1 other vertices, n number of vertices in graph. floyd-warshall algorithm more or less efficient, still, if don't need shortest paths between each pair of vertices or finding negative-length cycles, consider using priority queue finding shortest path between source , other vertices: https://en.wikipedia.org/wiki/dijkstra's_algorithm#using_a_priority_queue . or breadth first search can used if weights in graph e...

i found code on web. think can release managed items , make them available purchase again or need modification? seems i'm not able test correctly. looks need test button release managed items. on right track or totally misguided ? need opinion please don't have release managed items ... public void consumeallolderitems() { bundle owneditems = null; try { owneditems = mhelper.mservice.getpurchases(3, sgame.getcontext().getpackagename(), "inapp", null); } catch (remoteexception e1) { // todo auto-generated catch block e1.printstacktrace(); } int response = owneditems.getint("response_code"); if (response == 0) { alertnonstatic("consumeallolderitems() google responded ok our consumables"); arraylist<string> ownedskus = owneditems.getstringarraylist("inapp_purchase_item_list"); arraylist<string> purchasedatalist = owneditems.getstringarraylist(...
