I really got solution, after changing criteria ( for case | s * v | <= 1e-6 ). I can't set lower bounds as 0. Because this example is only one situation ( in common case: bounds for different variables are differed). But now I can calculate solution (though need around 10 minutes). It already is good. There are solvers which can calculate my problem faster, but I sought just java - lib.

The result is a very slow convergence. Other solvers might handle this special case better, and we should also aim to improve here.

-
This problem is related with systems biology. This models are saved in
SBML-format. And there are special Matlab TOOLBOX (COBRA) for solving this
problem (http://opencobra.sourceforge.net/openCOBRA/Welcome.html).
If you want to test this toolbox. I attached file AdipocyteModel.xml with model
(this model have same non-bounds constraints and object function like previous
example). You can instal COBRA toolbox and make next calculation in Matlab:
model = readCbModel('AdipocyteModel.xml');% read model
changeCobraSolver('glpk');% choose
solver
FBAsolution = optimizeCbModel(model,'max'); % solve
As I understand this solver use modification of simplex method (But I could be
wrong). Calculation time is around 1s.

[jira] [Commented] (IO-279) Tailer erroneously considers file as new

Robert Olofsson commented on IO-279:
I stumbled across this issue while tailing a file on a remote server via Samba.
The clock on the server was running a few seconds ahead of my local machine
which caused the file to be seen as newer even though it wasn't.
I solved this by simply replacing the line:
last = System.currentTimeMillis();
With:
last = file.lastModified();
That way it doesn't matter if the clocks are not in perfect sync.

Robert Olofsson commented on IO-269:
I came across this issue and noticed an inefficiency in the code of the run
method.
With the reOpen flag set a new RandomAccessFile is always created at the end of
the main while loop in the run method:
if (getRun() && reOpen) {
reader = new RandomAccessFile(file, RAF_MODE);
reader.seek(position);
}
This is unnecessary and contributes to unnecessary file locking on Windows.
If the reOpen flag is set a new RandomAccessFile should only be created when
the length of the file or the last modification date indicate that the file
needs to be read.

bq. First patch provides the capability.
Regarding the first patch, is it necessary to introduce a new method
"getAcceptedObservations()"? It would be nicer to consider that the wrapper
transparently modifies the problem (by changing the weights of some
observations, or removing them altogether) so that, viewed from the outside, it
would be like a fresh problem was built in the first place (with the modified
observations).
For example, one would be able to tell that some observations were deleted by
taking the difference between calls to "getObservationSize()" on the original
instance and on the wrapped instance.
Does that make sense?
{quote}
Getting the number of accepted or rejected observations is the part I am a
little unsure of. The second patch adds "getAcceptedObservations()" to the
Evaluation interface so that data editing is a simple wrapper.
Since the number of accepted observations can change from one Evaluation to the
next, I couldn't just use LSP.getObservationSize(). Since the current
optimizers aren't set up to support a changing observation size, I didn't want
to change the dimension of the residuals or the Jacobian either.
That left zeroing out the bad data and adding a method to Evaluation to get the
number of accepted/rejected observations. We could rename
Evaluation.getAcceptedObservations() to Evaluation.getObservationSize() if that
makes it clearer that it returns the length of the residual vector when there
is no data editing and the number of accepted observations when there is data
editing. E.g.
{code:java}
LeastSquaresProblem lsp = ...;
Optimum optimum = optimizer.optimize(lsp);
double acceptedRatio = optimum.getAcceptedObservations() /
lsp.getObservationSize();
{code}
Does this answer your question? I'm not sure if I understood correctly.

bq. This is unnecessary and contributes to unnecessary file locking on Windows.
On the contrary, it is an essential part of unlocking the file on Windows when
possible.
The full code is as follows:
{code}
if (reOpen) {
IOUtils.closeQuietly(reader);
}
Thread.sleep(delayMillis);
if (getRun() && reOpen) {
reader = new RandomAccessFile(file, RAF_MODE);
reader.seek(position);
}
{code}
Notice that the file is closed - and therefore unlocked - during the sleep if
reOpen is true.
If reOpen is false, the file remains locked by Windows for the duration of the
Tailer thread.

[jira] [Commented] (MATH-1105) Least squares statistical data editing
[ https://issues.apache.org/jira/browse/MATH-1105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13920923#comment-13920923 ] Gilles commented on MATH-1105: -- bq. Since the number of accepted observations can change from one Evaluation to the next, I couldn't just use LSP.getObservationSize(). Since the current optimizers aren't set up to support a changing observation size, I didn't want to change the dimension of the residuals or the Jacobian either. That's a key design issue. Does it makes sense for the "LeastSquaresProblem" instance to change the number of observations? According to the feature discussed here, it seems that the answer could be yes. If so, the optimizer cannot assume that the number of observations is constant. On the other hand, if we consider that changing an optimizer code to allow for a changing number of observations is not standard practice, that should be explicitly reflected in the handling of bad data, i.e. no observation can be removed, only its weight can be altered. Then, "getAcceptedObservations()" is not enough to convey the transformation which the handler applied on bad data; only the weights differences (between the original and the wrapper instances) will provide the full story. Hence, it seems that adding this method complexifies the API without a clear benefit. > Least squares statistical data editing > -- > > Key: MATH-1105 > URL: https://issues.apache.org/jira/browse/MATH-1105 > Project: Commons Math > Issue Type: Improvement >Reporter: Evan Ward > Attachments: 0001-Add-statistical-editing-capability.patch, > 0002-Integrate-data-editing-with-the-LS-framework.patch > > -- This message was sent by Atlassian JIRA (v6.2#6252)

[jira] [Commented] (IO-269) Tailer locks file from deletion/rename on Windows

There is no need to open the file unless changes to it's length or last modified date are detected. I've created a modified version of Tailer for small desktop app called SwingTail (http://unlogic.se/projects/swingtail) the incorporates these changes among others. However I've done so many other changes that I couldn't generate a clean diff. But the source is available here: svn://svn.unlogic.se/swingtail/trunk/src/se/unlogic/swingtail/Tailer.java Essentially I simply removed the open statement from the end of the loop and added three separate open statements higher up the loop that only open the file when a change is actually detected. > Tailer locks file from deletion/rename on Windows > - > > Key: IO-269 > URL: https://issues.apache.org/jira/browse/IO-269 > Project: Commons IO > Issue Type: Bug >Reporter: Sebb > Fix For: 2.4 > > Attachments: IO-269-v2.patch, IO-269-v3.patch, IO-269.patch, > ReOpen.java > > > The Tailer code works on Windows, except that it locks the file against > deletion or rename. > The test code fails to detect this, because it fails to check if the file > deletion succeeds. > This seems to be a Windows OS issue. > A possible solution might be to keep closing and re-opening the file. -- This message was sent by Atlassian JIRA (v6.2#6252)

--
Summary: AbstractFileObject.getURL() returns flaky URL object
Key: VFS-515
URL: https://issues.apache.org/jira/browse/VFS-515
Project: Commons VFS
Issue Type: Bug
Affects Versions: 2.0, 2.1
Environment: OSX 10.9.2
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
Reporter: Shon Vella
URL returned is created with constructor that expects host as a separate
parameter from path and passes in empty string for host. As a result subsequent
calls to url.getHost() returns an empty string rather than the host encoded in
the path.
Test Code
FileSystemManager fsManager = VFS.getManager();
FileObject f = fsManager.resolveFile("ftp://localhost/etc/hosts";);
URL url = f.getURL();
String host = url.getHost();
assertEquals("localhost", host);

It is just easier to have it on the ML. This is partly just personal preference - I use a thread-aware mail client and it is easier to actually talk to each other when threading and quoting happen automatically. > Least squares statistical data editing > -- > > Key: MATH-1105 > URL: https://issues.apache.org/jira/browse/MATH-1105 > Project: Commons Math > Issue Type: Improvement >Reporter: Evan Ward > Attachments: 0001-Add-statistical-editing-capability.patch, > 0002-Integrate-data-editing-with-the-LS-framework.patch > > -- This message was sent by Atlassian JIRA (v6.2#6252)
[jira] [Resolved] (NET-527) Add SimpleNTPServer as example and for testing
[ https://issues.apache.org/jira/browse/NET-527?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Sebb resolved NET-527. -- Resolution: Fixed Fix Version/s: 3.4 Thanks very much! I'd overlooked that the server was under the examples package rather than in the main code; I think it's fine there so I left it alone.
