PX2 is an MV*, Backbone-like framework with a more consistent design:. If you don't like the fact you can't have collections of collections or that views and collections can't have settable members in Backbone, then PX2 is for you.

QUESTION
I'm learning how to use PDDL for a IA class and I have to code a plan where I need to pick a person up from location4 and drop it in location1, also pick a person in location3 and drop it in location1 also. I already have the code which move to location pick the person, move to destiny location and drop it. but there are some rules that I can't put on code, there is a connection path that I need to follow and I do not know how to put that conditions:
This is the connection path: Loction1 -> Location2 -> Location4 -> Location3
I have the code to go from one location to other but I do not know how to put a condition in where it can't go from Location 1 to Location 4 directly
Here is the code:
Domain:
(define (domain planeacion_Str)
...ANSWER
Answered 2021-Jun-01 at 17:12You need to add a precondition to your movement action that you can only move between adjacent locations; and you then add a list of adjacent locations as predicates in your initial state:
(adjacent location1 location2)
(adjacent location2 location3)
but not (adjacent location1 location4).
QUESTION
I have a matrix of probability. Each row is the probability that observation i is fall in level 1, 2, 3. For example, row 1: this represent the first observation fall in level1 with probability = 0.2 , level2 = 0.3, and level3 = 0.5. At the end I want to get a column using the probability matrix to locate each observation to level 1,2, or 3, something similar to 1,2,3,3,2,.......
I tried to use rmultinom by sampling one sample from each row with the corresponding probability, but I'm not sure if it is the correct way or there is a better method.
ANSWER
Answered 2021-Jan-17 at 21:15Yes, in your example, that output means you sampled the first observation as falling into level 2. Using rmultinom is okay, but it would probably be more convenient to use the sample function:
QUESTION
I have created a Moodle Formulas questions in the field of kinematics with two boards. While I managed to get simpler questions with only one board to work flawlessly, the problem with this question is that the bound values are not inserted into formula's input entry fields. Consequently, the student cannot submit an answer because, effectively, nothing has been filled out. The rest of the question works though, as can be seen when the correct answers are filled in the question's preview.
I provide a Moodle XML file to make it easier to reproduce the problem: questions_formulas_JSXGraph_2boards.xml
You need a current version of Moodle with JSXGraph filter and question type Formulas installed.
The main JSXGraph code is this:
...ANSWER
Answered 2020-Dec-15 at 16:40In fact, it is correct that our filter in combination with formulas does not work correctly with multiple boards. At the moment, only one board ID is transferred to the JSXQuestion object and thus and thus it (and formulas) does not know anything about the second board. That is also one of the problems your example raises.
In addition, the boards actually have to be initialized with the JSXQuestion.initBoard() method for the bindInput() method to work. In the end, that's the root problem why your example doesn't work.
I will dedicate myself to this issue after the Christmas holidays and will be releasing a new version of the Moodle filter in January. Maybe there will be something new from JSXGraph by then, too.
Unfortunately, I can't offer you a dirty hack until then, as it requires a few basic changes to the filter.
I hope to be able to tell you more in January. Have a nice Christmas and stay healthy!

QUESTION
I would like to have two graphs, a x(t)-graph and a v(t)-graph. Students shall be able to move some points around in the v(t)-graph. At the same time, gliders in the x(t)-graph should be synchronized such that their time coordinates are bound to the points in the v(t)-graph.
I have got most of it working, see jsfiddle. The x(t)-graph, however, only updates when some element in it is touched. But I would like the gliders to move together with the points in the v(t)-graph. Is this possible?

Hello I'm Drawing a line in my Application . I'm using Caliburn.Micro MVVM Framework . In my DICOM image I'm able to draw a line using Pointer and Calculate distance . I use 3 events MouseDown,MouseMove and MouseUp. I left click to my Mouse and then I move if I release I able to Draw . My problem is when I move my mouse may be it sometimes change direction that time using Graphics.Drawline draw line but when I'm in the last point it should the Straight line . But as I move my Mouse it has the other point the line too that does not belong to this Line . Please see the what I did
It should be a starigh line as Sometimes My mouse move the color still at that point .There is a famous DICOM Viewer App Name Radiant Here you can see Line is Straight. Here is My code
...ANSWER
Answered 2020-Sep-15 at 10:50You should probably not draw directly on the image. This is quite inefficient, and you will also have problems like you have encountered. A better approach would be to create an overlay with lines and other graphics, See the question how to bind lines to a canvas on an example how to do this.
If you put your items control and your image in the same grid the items control should work like an overlay. i.e.
