Hi, We have seen a huge performance drop in 1.6.3, due to the checksum being enabled by default. I looked at the algorithm being used, and it is actually a CRC32, which is a very strong algorithm for detecting all sorts of problems, such as single bit errors, swapped bytes, and missing bytes. I''ve been experimenting with using a simple XOR algorithm. I''ve been able to recover

Let us consider the current uniform sampling without replacement algorithm. It resides in function do_sample in https://svn.r-project.org/R/trunk/src/main/random.c Its complexity is obviously O(n), where the sample is selected from 1...n, since the algorithm has to create a vector of length n. So when the sample size is much lesser than n, the algorithm is not effective. Algorithms with

Hi When I type: > ?nls I come across this section: algorithm: character string specifying the algorithm to use. The default algorithm is a Gauss-Newton algorithm. Other possible values are '"plinear"' for the Golub-Pereyra algorithm for partially linear least-squares models and '"port"' for the 'nl2sol'

Hi, Is in R any "fast" algorithm for correlation? What I mean is: I have very large dataset (microarray) with 55000 rows and 100 columns. I want to count correlation (p-value and cor.coef) between each row of dataset and some vector (of course length of this vector is equal to number of columns of dataset). In short words: For t-test we have: "normal" algorithm - t.test

This was posted not too long ago on sci.crypt... Enjoy... I think the most relevant information is near the top, but it''s all quite good... :-) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- There is no intrinsic difference between algorithm and data, the same information can be viewed as data in one context and as algorithm in another. Why then do so many people claim that encryption algorithms

I am looking for packages that can run a branch-and-bound algorithm to maximize a distance measure (such as Bhattacharyya or Mahalanobis) on a set of features. I would like this to be learning algorithm independent, so that the method just looks at the features, and selects the subset of a user-defined size that maximizes a distance criteria such as those stated above. Can anyone give some

Hi Jakob, Thanks for a very interesting description of the new register allocation algorithm in LLVM!!! Could you elaborate a bit on the following topics: 1) Do you have any plans to publish something more formal and detailed about this algorithm, e.g. a paper or something similar?  It would be nice to better understand how this algorithm relates to well-known algorithms described in the

There is no hash algorithm associated with SSH keys. The key format for RSA keys is always ?ssh-rsa?, and it is capable of being used with any of the available signature algorithms (ssh-rsa for SHA-1 and rsa-sha2-256 or rsa-sha2-512 for SHA-2). See section 3 in https://www.rfc-editor.org/rfc/rfc8332: rsa-sha2-256 RECOMMENDED sign Raw RSA key rsa-sha2-512 OPTIONAL

A few questions regarding the OpenSSH support for the Diffie Hellman key exchange algorithms: (1) Are the diffie-hellman-group-exchange-sha256", "diffie-hellman-group-exchange-sha1" , "diffie-hellman-group14-sha1" "diffie-hellman-group1-sha1" (as defined in RFCs 4253 and RFC 4419) the complete list of key exchange algorithms supported by OpenSSH? (2) Is there a

Hello, I have a question about multichannel and the load-balancing algorithm. What kind of algorithm is it? (Roud-robin, dynamic round-robin, ...) What are the arguments the algorithm compute to load-balance the network traffic on the interfaces? I already know that if a 10Gb/s interface and a 1Gb/s interfaces are in the multichannel connection the 1Gb/s one will be ignored until the 10Gb/s goes

See, I have built my own genetic algorithm already and tested it on this problem. I have a solution, but due to the heuristic nature of GA, I cannot guarantee that it is the optimal subset. If I was simply doing this for a company project, you are spot on with the type of algorithm I would use, but I am doing this for a scientific paper. I need to be able to find the optimal subset over my

Dear all, I would like to use the Levenberg-Marquardt algorithm for non-linear least-squares regression using function nls.lm. Can anybody help me to find a a way to compute confidence intervals on the fitted parameters as it is possible for nls (using confint.nls, which does not work for nls.lm)? Thank you for your help Michael

Hi, I am just starting up on SPEEX AEC algorithm and have couple of questions around echo cancelation algorithm used in SPEEX. 1) Usually Echo Cancelation Algorithm has support for number of components ? - Non-Linear Processor (NLP) - Automatic Microphone Gain Control (AGC) - Transducer Equalization (EQ) - Dynamic Range Compression (DRC) - Ambient
