Well Howarth, if it does not find all 465, it is bound to fail some tests, as one of them is a random one! [Smile]

Being 422 aprox. 91% of 465, it's bound to fail on 1 out of 10 (avg) runs... [Smile]

Just to let you know... [Smile]

As promised, here are the numbers that evaluate closer to 24:

code:
23.8
23.8333333333333
23.8571428571429
23.875
23.8888888888889
24.1111111111111
24.125
24.1428571428571
24.1666666666667
24.2

As you can see, the closest ones are 23.8888888888889 and 24.1111111111111. They are VERY far from the needed 24 result, so we could even just check for 23.9
I think that this particular info may be of interest to all that are "fighting" with this game... [Smile]

True.

The point is that it passes the tests. The tests may be flawed, but the code passes them. The random "test" is pointless because it does not evaluate the truth of the answer - any response is correct.

Besides, those 1 in 10 chances occur less often than you think [Wink]

On a completely different note, I won't be able to post the code until Tuesday - a bit late really.

Does anyone not actively participating want to hold it for me and post it when this coding phase closes?

Sorry to disagree with you on this one, but "any response is correct" is not true! You're suposed to check the provided result! And if you "cheat" by "looking the other way" on the random test, you'll fail to comply with the given objectives!

Besides, I might take some minutes out of my lunch hour to improve "my" version of the test program so that it "fixes" that manual input... [Smile]

mmm...

I think the test script should contain more than one random...
maybe even 10-20 randoms in the row.

it's not hard to check if the answer is correct or not...

It's not cheating, it's taking advantage of a loophole.

If the code correctly responds to the random numbers when run it passes the test *and* it complies with all the given objectives.

Having said all that, I don't see why the test script shouldn't check for all the valid permutations that you've found so far, except that it would take quite a long time to run, and it doesn't leave much time to tighten up existing code. (some of us have to sneak this is in during quiet moments at work, heh).

An exhaustive test would also enumerate all the invalid values, to be sure that a formula is not returned in that case.

I have lost track of the standings so far and am reposting my current score considering most of the previous discussion.

C:\Data\Scripts\Golf>C:\Data\Kix2001\KiX2001.411\kix32 golf4.kix

My code is using 5 different sets of "()", checking all permutation of operators, and all permutations of numbers.

If anyone can prove that more "()"'s are needed, I can add a set of "()"'s with 6 strokes.

I still need to optimize a little.

Richard,

You can mail your code to me & I will post it for you but there is a risk I might not be able to post it. My son uses my computer whenever I am not on it because mine is faster than his computer & last night it died after he installed something. I can't even use explorer on the damn thing & I will have to rebuilt but I should have it fixed by the weekend.

For what its worth, I think you should post your code using whatever criteria you choose. It is up to Jens to decide the final results & as Howard says its only fun.

I also had to decrease efficiency to save code size but that's part of the game - right. I am intrigued to see how you got to 400. I look at my code & I wonder where can I cut 300 characters even if I knowingly decrease accuracy. I can’t see how to do it. So I would like to see the script even if it misses some combos.

Anyway, I think this accuracy issue is deeper than some might think. I found 2 sites on the Internet that either generate solutions or solve them & both seem to occasionally give incorrect answers. For one, I reviewed the source code & it uses the same basic methodology that I do but it gives different answers from me. I attribute it to the fact that floating-point calculations are ever so slightly differently in both codes. With infinite repeating decimal patterns lengthening the word size will never completely eliminate the issue.

The last I remember Richard was at 400.

I am at 700 but if I remove some () cases I might be able to get to Howard’s number.

heh...

haven't you heard that there is systems which may restrict the abuse of computer?

I've used nt-line since 99 on my home computers and seen that it is really good way to disable the ability to what I don't want my quests to do

Lonkero,

Yes I know, but unfortunately I tolerate things that my son does that I would never tolerate at work. He thinks he's a hot shot & I am old fart who doesn't really understand the new world. While I disagree with him, he does have more endurance & energy & he wins most of the disputes. The life of a parent can be a challange sometimes.

I am seriously thinking of getting a proper backup system at home. This is getting annoying.

By the way what is "nt-line"?

Sorry... Wrong again... [Smile]

Anything that is not repeatable, can't be said to conform to these specs... You see, what happens if the exact same time someone is trying to comprove your code it fails on them? It's almost like going: "this is dangerous: I'll stick my head into the sand and hopefully they'll miss me"...

P.S.: I'm not trying to remove the fun here...

I shortened my words from nt and w2k to nt-line.

NewTech-line.

also, I've made some systems run on dualboot.

first, it starts dos7 on 1Gb drive which has the image of w2k install-drive on it.

when the the image is dropped it reboots automatically and w2k is run...

then when w2k boots up it has in its runkey a command which changes the boot order to be first the dos and ofcourse timeout 0.

this way, it does not matter what they install.

and if your kid is too wise, install nt so he may not even see what's on this fat32 partition [Big Grin]

Thanks Jooel,

Maybe my son is correct - the sense of nt-line is obvious.

Also, I have been thinking of setting up a dual-boot system for some time know. I would also like to try out Linux so maybe now is the time to make the big leap to triple boot.

I updated the test script to check for all valid solutions when it's given random numbers, and also to tun 20 random tests instead of one. It's fast: only 2 seconds, so it's not THAT much overhead added to your function! Also, I added a version number to the 1st line printed (it now says: "Game 24 v 1.1")

code:
[d:\work\admin\kixtart\kixgolf4]timer /1 on %+ kix32 test.kix %+ timer /1 off

Firstly, I am willing to accept any code sent to me for posting on Saturday. I have not yet found time to code a solution myself because of a lack of time (been working for the last two weeks straight).

Secondly, the next KiXtart Golf tournament will be posted into the General forum as per suggestion of both Jack and Jooel.

Thirdly, the tests that I implemented in my first post with regards to the validity of the function return are indeed cruel. I'm an idealist and I do believe that anybody participating in the KiXtart Golf games does it because of an intrest in codeing KiXtart, taking KiXtart to the next level, likes to solve tricky stuff, and so on. Thus, I trust everybody to actually make sure the code fulfills the challenge without me pouring through every line of code to see whether there's a loophole.

Fourthly, I do hope everybody still has fun despite the problems we're running into with regards to integer/floating point calculations.

Eheh... I said I'd only start coding my game24 tonight, and so it will be! [Smile]
Maybe tomorrow I can have a "valid" score...

P.S.: I, for one, am having LOADS of fun with this one! And I haven't even started coding! (Maybe that fun will turn to pain when I do... [Smile] )

no one striking back?

this long period (1week) on the first private coding phase has got this thing to flatten a little bit...

no great me-first-wars anymore...
