Im looking for the "SDPTools" package in Maple. Its mentioned here;
https://arxiv.org/abs/1112.6382
Any suggestions?
Are you possibly looking for the Dynamic Systems package? The SDPTools package is not in public domain, you can try to write to the developers at fguo#mmrc.iss.ac.cn
with(DynamicSystems);

I am a student who begin to study SHOP2 from China.
My teacher told me to run JSHOP2 in Eclipse.Now I can run original zenotravel problem and generate GUI and plans.Likewise, I want to put other domain and problems to SHOP2 and produce plans.
But the problem is that I don't know how to compile them and My teacher only asked me to run the the main function in Internaldomain but it can't succeed.Follow is the original code:
public static void main(String[] args) throws Exception
{
//compile();
// compile(args);
//-- run the planning algorithm
run(args);
}
This code can run zenotravel.Then I put domain and problems named pfile1 and
tdepots respectively into SHOP2 folder.Change the codes to:
{
compile(domaintdepots);
// compile(args);
//-- run the planning algorithm
run(args);
}
It warns "domainpdfiles cannot be resolved to a variable".
Or
//--compile();
compile(args);
//-- run the planning algorithm
//run(args);
It turns out:
"Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at JSHOP2.InternalDomain.compile(InternalDomain.java:748)
at JSHOP2.InternalDomain.main(InternalDomain.java:720)"
720 is main funcition above.And 748 is compile function:
public static void compile(String[] args) throws Exception
{
//-- The number of solution plans to be returned.
int planNo = -1;
//-- Handle the number of solution plans the user wants to be returned.
if (args.length == 2 || args[0].substring(0, 2).equals("-r")) {
if (args[0].equals("-r"))
planNo = 1;
else if (args[0].equals("-ra"))
planNo = Integer.MAX_VALUE;
else try {
planNo = Integer.parseInt(args[0].substring(2));
} catch (NumberFormatException e) {
}
}
Finally,according to the advice of the friend,I put the two pddls into src folder and use “java Jshop2.InternalDomain domaintdepots”in CMD commad but an error appeared:"the main class Interdomain can't be found or loaded".But I have set the class path accurately and the Zenotravel planning can run.So how
and where can I use the command ？
And what is written in the bracket"compile()" in Eclipse？
I am also not familiar with JAVA so it's better if there is concrete instruction.Thanks a lot.
Please describe what are you trying to build, what is it supposed to do, what is the expected end result.
If you do have a valid PDDL domain and problem file, you could try to load them into the online http://editor.planning.domains/ editor using the File > Load menu. Then press the Solve button and confirm which of the file is the domain and which is problem. If the PDDL model is valid (and the underlying solver can handle the requirements), you will get a plan back.
If you are trying to build a software solution that needs a PDDL-based planning engine as one of its component, perhaps you could use one of the available implementations: https://nergmada.github.io/pddl-reference/guide/whatisplanner.html#list-of-planners
If you are trying to build your own planning engine in Java using the Eclipse IDE, you probably need a Java-based PDDL parser. Here is a tutorial, how to use pddl4j for that purpose:
https://github.com/pellierd/pddl4j/wiki/A-tutorial-to-develop-your-own-planner
If you need to use Jshop2 in particular, it looks from their documentation (http://www.cs.umd.edu/projects/shop/description.html) that you need to indeed compile the domain and problem PDDL into Java code using following commands:
java JSHOP2.InternalDomain domainFileName
java JSHOP2.InternalDomain -r problemFileName
Edited on June 19th
Java package names (e.g. JSHOP2) and class names (InternalDomain) are case sensitive, so make sure you type them as per the documentation. That is probably why you are getting the "main class not found error".
It is difficult to say what the lines numbers 748 and 720 exactly correspond to, because in the GitHub repo https://github.com/mas-group/jshop2/blob/master/src/JSHOP2/InternalDomain.java the code is different from yours. Can you indicate in your questions which lines those are exactly?
The make file shows how to execute an out-of-the-box example in the distribution:
cd examples\blocks
java JSHOP2.InternalDomain blocks
java JSHOP2.InternalDomain -r problem300
Does that work for you?
2 problem with minspantree.m in Matlab 2018a
Hi dear all; I want to find a min-span-tree of a matrix. I figured that MATLAB's own minspantree.m may be the most efficient algorithm. So i use
open minspantree.m
And here comes Question:
1.The code in minspantree.m used G.EdgeProperties.Weight and G.Underlying. G is a graph object. But when I use G.EdgeProperties.Weight or G.Underlying in Command window, both returns error: Error using graph/subsref (line 15) No public property 'EdgeProperties' for class 'graph'. Why?
2.minspantree.m line 62：
[pred, edgeind] = primMinSpanningTree(G.Underlying, w, rootNode, restart);
Is primMinSpanningTree a function? But I can not find any: function [ ] = primMinSpanningTree() in minspantree.m, neither can I find primMinSpanningTree.m file in my whole disk. So what is primMinSpanningTree? What is its code? How can I find it and open it?
Thanks all very much.
Both EdgeProperties and Underlying are private properties of the graph class. They can only be accessed from within the class. Take a look at Graph.m. minspantree is a class method, so it has access.
primMinSpanningTree is a built-in method from matlab.internal.graph.MLGraph. You can see that with which primMinSpanningTree. So I believe the code might not be accessible.
I have installed caffe, uncommenting
WITH_PYTHON_LAYER=1
in 'Makefile.config'
When I use a python data layer in my net.prototxt, it says
Unknown layer type: Python
To cross check it in python interface,
I tried
import caffe
from caffe import layers as L
L.Python()
this seems to work ,no error then.
Where is the problem?
You can find out what layer types caffe has in python simply by examining caffe.layer_types_list(). For example, if you actually have a "Python" layer, then
list(caffe.layer_type_list()).index('Python')
Should actually return an index for its name in the layer types list.
As for L.Python() - this caffe.NetSpec() interface is used to programatically write a net prototxt, and at the writing stage layer types are not checked. You can actually write whatever layer you want:
L.YouDontThinkTheyNameALayerLikeThis()
Is totally cool. Even converting it to prototxt:
print "{}".format(L.YouDontThinkTheyNameALayerLikeThis().to_proto())
Actually results with this:
layer {
name: "YouDontThinkTheyNameALayerLikeThis1"
type: "YouDontThinkTheyNameALayerLikeThis"
top: "YouDontThinkTheyNameALayerLikeThis1"
}
You'll get an error message once you try to run this "net" using caffe...
This code contains the following tidbit:
from theano.tensor.nnet import conv2d
...
# convolve input feature maps with filters
conv_out = conv2d(
input=input,
filters=self.W,
filter_shape=filter_shape,
input_shape=image_shape
)
which raises an exception due to 'input_shape' not being found, despite being mentioned in the documentation where it says that:
"image_shape ... – Deprecated alias for input_shape"
Looking at conv.py both locally and in the source I found:
def conv2d(input, filters, image_shape=None, filter_shape=None,
border_mode='valid', subsample=(1, 1), **kargs):
Needless to say, there is no trace of input_shape.
If one modifies the code above as follows
# convolve input feature maps with filters
conv_out = conv2d(
input=input,
filters=self.W,
filter_shape=filter_shape,
image_shape=image_shape
)
, the exception disappears and the code runs fine.
What am I missing? If image_shape is deprecated, how come it works while input_shape does not?
Is the theano version at the repository obsolete?
PS: I would have liked to ask directly the folks at http://deeplearning.net, but I could not find how.
Are you sure you have the latest version installed?
conv.py contains the deprecated implementation of conv2d. The new implementation can be found in __init__.py
Make sure you are using the import statement
from theano.tensor.nnet import conv2d
and not
from theano.tensor.nnet.conv import conv2d
since the second one is going to import the deprecated implementation
I'm reading DICOM series using itk and converting them into VTK for visualization purposes. Even though I manage to visualize DICOM series in 3 different windows with 3 different orientations (XY, XZ and YZ) I can't even click on the windows. When I click or try to change the slice viewed, my code gives an access violation error. I'm using ImageViewer2 to visualize the slices. A file called itkVTKImageExportBase.cxx is opened when I try to find out what the error is. The lines referred to are:
void VTKImageExportBase::UpdateInformationCallbackFunction(void* userData)
{
static_cast<VTKImageExportBase*>
(userData)->UpdateInformationCallback();
}
My code is as follows:
typedef itk::VTKImageExport< ImageType > ExportFilterType;
ExportFilterType::Pointer itkExporter = ExportFilterType::New();
itkExporter->SetInput( reader->GetOutput() );
// Create the vtkImageImport and connect it to the itk::VTKImageExport instance.
vtkImageImport* vtkImporter = vtkImageImport::New();
ConnectPipelines(itkExporter, vtkImporter);
pViewerXY->SetInput(vtkImporter->GetOutput());
pViewerXY->SetSlice(3);
pViewerXY->SetSliceOrientationToXY();
pViewerXY->SetupInteractor(m_pVTKWindow_1);
pViewerXY->UpdateDisplayExtent();
m_pVTKWindow_1->AddObserver(vtkCommand::KeyPressEvent, m_pVTKWindow_1_CallbackCommand);
m_pVTKWindow_1->Update();
pViewerXZ->SetInput (vtkImporter->GetOutput());
pViewerXZ->SetSliceOrientationToXZ();
pViewerXZ->SetupInteractor(m_pVTKWindow_2);
pViewerXZ->UpdateDisplayExtent();
m_pVTKWindow_2->AddObserver(vtkCommand::KeyPressEvent, m_pVTKWindow_2_CallbackCommand);
m_pVTKWindow_2->Update();
pViewerYZ->SetInput (vtkImporter->GetOutput());
pViewerYZ->SetSliceOrientationToYZ();
pViewerYZ->SetupInteractor(m_pVTKWindow_3);
pViewerYZ->UpdateDisplayExtent();
m_pVTKWindow_3->AddObserver(vtkCommand::KeyPressEvent, m_pVTKWindow_3_CallbackCommand);
m_pVTKWindow_3->Update();
pViewerXX windows are imageviewer2 objects whereas m_pVTKWindow_X refers to wxVTK objects to use in wxWidgets GUI package.
Optional: My exporter and importer are as given below:
template <typename ITK_Exporter, typename VTK_Importer>
void ConnectPipelines(ITK_Exporter exporter, VTK_Importer* importer)
{
importer->SetUpdateInformationCallback(exporter->GetUpdateInformationCallback());

I don't have an exact answer to your question, but have you considered using one of the common medical image processing frameworks? There are a couple of them like MITK (mitk.org) or Slicer3D (slicer.org). They do a great job of linking together ITK, VTK and a sophisticated GUI Framework like QT (in the MITK case).
I have worked a long time in medical image processing and used MITK extensively. In my opinion, using a medical image processing framework really helps you focus on your real image processing problems, rather than trying to build processing/visualization pipelines for different types of visualizations.
If you look at InsightApplications, there are two methods:
The same as you tried, which is here, or
This one, which creates a pipeline object that can be connected on both sides. We're actually using this, and it works out quite well for us. You can copy this class into your code and use it.
There are some interesting usage examples in there too. Take a look at them and see if you can modify anything for your requirement.
Classes in the ITKVTkGlue module can be used to convert an ITK image to in a pipeline. See the tests for examples of how the classes are applied.
