One I can tell you is: [code=c]if (*array > ave) else if (*array < ave)[/code] Although this is inside the loop it'll always test only the first element of the array. To access other elements in the array you should use the subscript operator (operator []). Re: Tolerance 16 Years Ago by ithelp rather use C++ overload > < and == functions.

I've been toying around with fabs for a little bit, and cannot figure it out. It is late, and the assignment is due early. Can you just tell me what I should put? I would probably learn it quicker that way anyhow. Re: Tolerance 16 Years Ago by thekashyap [quote=shmay;362062] Can you just tell me what I should put?

Say I set tolerance to 3, my 1st and 6th results ((43… list and add/subtract values from 1 to 3 (my tolerance), so the entry (43,560) will result in: (43,560… Re: group tuple values with tolerance and average 7 Years Ago by JamesCherrill … it's trivial to find consecutive entries that are within tolerance for the first value. For each set of such entries… the second value and find the subsets that are within tolerance for the second value. Replace those subsets by their averages… Re: group tuple values with tolerance and average 7 Years Ago by Gribouillis You could try to compute a key for each pair `(x, y)`, the key could be `(x//3, y//3)` for a tolerance of 3. Then you sort the data by the key and you group together the points having the same key, using `itertools.groupby()`. You can then average the values in each group. Re: group tuple values with tolerance and average 7 Years Ago by Gribouillis … probably be determined by * The shape of the clusters * Your tolerance * The minimum and maximum values of the coordinates As I… Low tolerance here. 14 Years Ago by daveyb91 … the other one.

This isn'… Fault tolerance in JAVA 8 Years Ago by london-G … a project I have been asked to look into fault tolerance. From what I understand a fault tolerant program is a… Re: Fault tolerance in JAVA 8 Years Ago by Schol-R-LEA Actually, 'fault tolerance' has more to do with gracefully recovering from exceptional situations than with avoiding them entirely. Setting up exception blocks around fault-sensitive code (e.g., pretty much all I/O) is a good starting point, but not sufficient in and of itself; you have to know how to handle the exceptions, not just trap them. Re: Not meeting tolerance 14 Years Ago by riotburn No its not a matter of the precision of the variable as i have few other newtons method programs. I added another statement to the loop and get the answer i needed, though it seems like it should've met the tolerance without the extra statement. [CODE]while(abs(xnew - xold) > tol || abs(best-B) > tol)[/CODE] Re: group tuple values with tolerance and average 7 Years Ago by giancan Thanks Gribouillis, while waiting for some help I found another possible solution. from cluster import KMeansClustering cl = KMeansClustering(unique_ptlist) #unique_ptlist is my starting point's list clusters = cl.getclusters(8) filtered_list=[] for subcluster in clusters: filtered_list.append(((sum(x[0] … Re: group tuple values with tolerance and average 7 Years Ago by Gribouillis Or perhaps you could try n = len(set((x//tol, y//tol) for (x, y) in data)) as a rough estimate of the number of clusters. Re: group tuple values with tolerance and average 7 Years Ago by Gribouillis @JamesCherrill In your example my 'key' algorithm groups the 3s and the 5s in a one-liner because the keys x//3 for the values (1, 3, 3, 5 ,5, 5, 5) are (0, 1, 1, 1, 1, 1, 1). In python it gives >>> import itertools as itt >>> from functools import partial >>> data = [1, 3, 3, 5, 5, 5, 5] >>>… Re: group tuple values with tolerance and average 7 Years Ago by JamesCherrill Yes. My algorithm was 2d, just the illustration was 1d, and it extends to nD. But yours still looks a lot better :) JC ps what about 2,4,4,6,6,6,6 -> 1,1,1,2,2,2,2 Re: Low tolerance here. 14 Years Ago by crunchie It's in the rules that you agreed to when you signed up.

Re: Low tolerance here. 14 Years Ago by Tom Gunn [QUOTE]I get a warning just because I made a double topic, and had no idea about how to move the other one.[/QUOTE] You can probably go to the post you want to move and click the Flag Bad Post link to report it. That will get the moderators' attention, and because it was an accident and you reported it yourself, they should not give you a warning. Re: Low tolerance here. 14 Years Ago by happygeek The warning system provides a way of letting members know they have broken the rules without it actually giving them infraction points or being too formal - as it says, it simply serves as a reminder of the rules. It also says "We understand that you probably didn't intend to do something wrong" so don't take it as an intolerant slap but … Re: Low tolerance here. 14 Years Ago by MosaicFuneral [QUOTE=Tom Gunn;958827]You can probably go to the post you want to move and click the Flag Bad Post link to report it.

What you can do, however, is anticipate them. Anticipate every single error that might occur, and implement decent error and Exception handling for them.
