I say that C has a large vantage arsenic it makes use of agelong for the calculations and not arbitrary dimension integers arsenic the another 3. Besides it doesn’t demand to burden a runtime archetypal (Bash the others?).

Motion 1: Bash Erlang, Python and Haskell suffer velocity owed to utilizing arbitrary dimension integers oregon don’t they arsenic agelong arsenic the values are little than MAXINT?

Motion 2: Wherefore is Haskell truthful dilatory? Is location a compiler emblem that turns disconnected the brakes oregon is it my implementation? (The second is rather possible arsenic Haskell is a publication with 7 seals to maine.)

Motion three: Tin you message maine any hints however to optimize these implementations with out altering the manner I find the components? Optimization successful immoderate manner: nicer, sooner, much “autochthonal” to the communication.

EDIT:

Motion four: Bash my useful implementations license LCO (past call optimization, a.okay.a process recursion elimination) and therefore debar including pointless frames onto the call stack?

I truly tried to instrumentality the aforesaid algorithm arsenic akin arsenic imaginable successful the 4 languages, though I person to acknowledge that my Haskell and Erlang cognition is precise constricted.

Origin codes utilized:

#see <stdio.h> #see <mathematics.h> int factorCount (agelong n) { treble quadrate = sqrt (n); int isquare = (int) quadrate; int number = isquare == quadrate ? -1 : zero; agelong campaigner; for (campaigner = 1; campaigner <= isquare; campaigner ++) if (zero == n % campaigner) number += 2; instrument number; } int chief () { agelong triangle = 1; int scale = 1; piece (factorCount (triangle) < 1001) { scale ++; triangle += scale; } printf ("%ld\n", triangle); } 

#! /usr/bin/env python3.2 import mathematics def factorCount (n): quadrate = mathematics.sqrt (n) isquare = int (quadrate) number = -1 if isquare == quadrate other zero for campaigner successful scope (1, isquare + 1): if not n % campaigner: number += 2 instrument number triangle = 1 scale = 1 piece factorCount (triangle) < 1001: scale += 1 triangle += scale mark (triangle) 

-module (euler12). -compile (export_all). factorCount (Figure) -> factorCount (Figure, mathematics:sqrt (Figure), 1, zero). factorCount (_, Sqrt, Campaigner, Number) once Campaigner > Sqrt -> Number; factorCount (_, Sqrt, Campaigner, Number) once Campaigner == Sqrt -> Number + 1; factorCount (Figure, Sqrt, Campaigner, Number) -> lawsuit Figure rem Campaigner of zero -> factorCount (Figure, Sqrt, Campaigner + 1, Number + 2); _ -> factorCount (Figure, Sqrt, Campaigner + 1, Number) extremity. nextTriangle (Scale, Triangle) -> Number = factorCount (Triangle), if Number > a thousand -> Triangle; actual -> nextTriangle (Scale + 1, Triangle + Scale + 1) extremity. lick () -> io:format ("~p~n", [nextTriangle (1, 1) ] ), halt (zero). 

factorCount figure = factorCount' figure isquare 1 zero - (fromEnum $ quadrate == fromIntegral isquare) wherever quadrate = sqrt $ fromIntegral figure isquare = level quadrate factorCount' figure sqrt campaigner number | fromIntegral campaigner > sqrt = number | figure `mod` campaigner == zero = factorCount' figure sqrt (campaigner + 1) (number + 2) | other = factorCount' figure sqrt (campaigner + 1) number nextTriangle scale triangle | factorCount triangle > one thousand = triangle | other = nextTriangle (scale + 1) (triangle + scale + 1) chief = mark $ nextTriangle 1 1 

Utilizing GHC 7.zero.three, gcc four.four.6, Linux 2.6.29 connected an x86_64 Core2 Duo (2.5GHz) device, compiling utilizing ghc -O2 -fllvm -fforce-recomp for Haskell and gcc -O3 -lm for C.

• Your C regular runs successful eight.four seconds (quicker than your tally most likely due to the fact that of -O3)
• The Haskell resolution runs successful 36 seconds (owed to the -O2 emblem)
• Your factorCount' codification isn’t explicitly typed and defaulting to Integer (acknowledgment to Daniel for correcting my misdiagnosis present!). Giving an express kind signature (which is modular pattern anyhow) utilizing Int and the clip modifications to eleven.1 seconds
• successful factorCount' you person needlessly known as fromIntegral. A hole outcomes successful nary alteration although (the compiler is astute, fortunate for you).
• You utilized mod wherever rem is sooner and adequate. This adjustments the clip to eight.5 seconds.
• factorCount' is perpetually making use of 2 other arguments that ne\’er alteration (figure, sqrt). A person/wrapper translation provides america:

$ clip ./truthful 842161320 existent 0m7.954s person 0m7.944s sys 0m0.004s 

That’s correct, 7.ninety five seconds. Persistently fractional a 2nd quicker than the C resolution. With out the -fllvm emblem I’m inactive getting eight.182 seconds, truthful the NCG backend is doing fine successful this lawsuit excessively.

Decision: Haskell is superior.

Ensuing Codification

factorCount figure = factorCount' figure isquare 1 zero - (fromEnum $ quadrate == fromIntegral isquare) wherever quadrate = sqrt $ fromIntegral figure isquare = level quadrate factorCount' :: Int -> Int -> Int -> Int -> Int factorCount' figure sqrt candidate0 count0 = spell candidate0 count0 wherever spell campaigner number | campaigner > sqrt = number | figure `rem` campaigner == zero = spell (campaigner + 1) (number + 2) | other = spell (campaigner + 1) number nextTriangle scale triangle | factorCount triangle > a thousand = triangle | other = nextTriangle (scale + 1) (triangle + scale + 1) chief = mark $ nextTriangle 1 1 

EDIT: Truthful present that we’ve explored that, lets code the questions

Motion 1: Bash erlang, python and haskell suffer velocity owed to utilizing arbitrary dimension integers oregon don’t they arsenic agelong arsenic the values are little than MAXINT?

Successful Haskell, utilizing Integer is slower than Int however however overmuch slower relies upon connected the computations carried out. Fortunately (for sixty four spot machines) Int is adequate. For portability interest you ought to most likely rewrite my codification to usage Int64 oregon Word64 (C isn’t the lone communication with a agelong).

Motion 2: Wherefore is haskell truthful dilatory? Is location a compiler emblem that turns disconnected the brakes oregon is it my implementation? (The second is rather possible arsenic haskell is a publication with 7 seals to maine.)

Motion three: Tin you message maine any hints however to optimize these implementations with out altering the manner I find the components? Optimization successful immoderate manner: nicer, quicker, much “autochthonal” to the communication.

That was what I answered supra. The reply was

• zero) Usage optimization through -O2
• 1. Usage accelerated (notably: unbox-capable) sorts once imaginable
• 2. rem not mod (a often forgotten optimization) and
• three) person/wrapper translation (possibly the about communal optimization).

Motion four: Bash my purposeful implementations license LCO and therefore debar including pointless frames onto the call stack?

Sure, that wasn’t the content. Bully activity and gladsome you thought-about this.
