kandi X-RAY | frontier Summary
Frontier is an experimental edge processing platform for the Internet of Things (IoT) that aims to provide high-throughput data-parallel processing across multiple edge devices. Further details on Frontier, including a paper that explains the underlying model, can be found at the project website. The research that lead to Frontier was sponsored by the ITA project. Frontier is licensed under EPL (Eclipse Public License). The Frontier system is under heavy development and should be considered an alpha release. This is not considered a "stable" branch. Frontier builds on previous research into data-parallel stream processing for datacenter environments as part of the SEEP project, albeit heavily modified to operate in an edge environment.

QUESTION
When I run my code it throws a segmentation fault and I have tried rewriting the code several times. Still to no avail, it won't even run. The segmentation fault happens as soon as my program is launched. What it's supposed to do is print a path on screen using the ncurses library in Linux, from the given coordinates. Here is the problematic snippet with the lines where gdb said the segmentation fault was, also it (snippet) reproduces the problem.
EDIT: This will help explain what I'm trying to do, but using dynamic arrays. Breadth First Search
EDIT 2: The variable frontier is supposed to keep track of the X and Y values at a specific index. The add_neighbors function is there to add all four neighbors (providing they aren't already added) to the frontier and came_from arrays.
frontier[index][0] is X value.
frontier[index][1] is Y value.
The before the first while loop I set the start position x1 and y1. During the first while loop, it increments getting the new coordinates from the frontier, then processing and adding to came_from array.
For example:
(x1,y1) (x1+1,y1)
(x1,y1+1) (x1+1,y1+1)
(x1,y2) (x2,y2)
I'm trying to get from (x1,y1) to (x2,y2). Sure hope that explains it better. What I'm trying to implement is a Breadth First Search (BFS) algorithm. Using two arrays, one is frontier (keeps track of visited positions) and came_from (keeps track of X and Y the path from x1,y1 to x2,y2). Updated the code to reflect the first answer. Plus added a comment to explain where the error might be, not really sure but I've been debugging it. It looks like the came_from array never gets set with x and y.

Answered 2021-May-17 at 16:33How can I solve this issue?
The memory available for automatic objects is typically very limited. As such, you must allocate all huge objects dynamically. Otherwise your variables will likely consume all of the memory reserved for automatic objects, which results in ... stack overflow.
Having huge member variables would not be a problem if all instances of the class were allocated dynamically, but since that restriction is hard to enforce, it is usually best to simply not have huge member variables.
Your arrays vis and frontier_vis are huge. Simple solution: Use std::vector.
QUESTION
I am facing problems with a line (indicated with hashes below in Global.R). I'm currently working on a finance related R shiny app. One of the tabs includes a checkboxgGroupInput which lists all the columns of my source file except Date, which are the names of stocks/indexes which I can select to be included in the ggplot below.
Sample dataset of source_file would look something like this:
Date Index 1 Index 2 Index 3 Index 4 Index 5 2016-01-01 +5% -2% +5% +10% +12% 2016-01-08 +3% +13% -8% -3% +10% 2016-01-15 +2% +11% -3% +4% -15%In this case, the check box would load up 5 options, Index 1 to Index 5. I envision that I will be able to select Index 2 and 3, and that would generate a plot involving the 2 variables selected (Index 2 and 3). However, I'm unsure as to how I should be writing the code with reference to the output of checkboxGroupInput
I tried to do the following to reference the first and last values of the output from checkboxGroupInput but it seems to not be working.

QUESTION
I'm writing an R shiny application. I'm facing much trouble, particularly the checkboxGroupInput function. I'm hoping that I will be able to create a dynamic list that will automatically list down all columns except the first column, source_file$Date of a dataset named source_file, and I'm not entirely sure on it. Would greatly appreciate any help you can provide!
Sample dataset of source_file would look something like this:
Date Index 1 Index 2 Index 3 Index 4 Index 5 2016-01-01 +5% -2% +5% +10% +12% 2016-01-08 +3% +13% -8% -3% +10% 2016-01-15 +2% +11% -3% +4% -15%The end goal is that I hope the checkboxGroupInput function will be able to automatically read all columns starting from the second column (ignore Date). In this case, the check box would load up 5 options, Index 1 to Index 5. It should be replicable such that it can load any number of indexes depending on the data specified. I tried hard-coding each individual index in but it's definitely counter-intuitive and so frustrating to do.

I am using Python's Queue.PriorityQueue (in an implementation of the A* algorithm, though I'm not sure if this is relevant). I'm using it to hold objects that are non-comparable (an object class provided by a professor that I cannot modify), and Python throws an error when it tries to add an priority-object tuple (ex. pq.put(1, object)) when it's already holding a tuple with the same priority.
This is the relevant part of the error:

Answered 2021-Mar-03 at 00:23Ok, just in case someone ends up here, I ended up taking superb rain's comment into consideration since I was looking for a simpler solution, and I didn't really have time to overhaul my solution to make it more efficient or better. I just needed something to work.
The solution was basically just implement the suggestion here. If there's anyone that's looking at this that just really doesn't understand how Python works (like me!), stick this at the top.

Answered 2021-Feb-13 at 20:36The standard approach is to use t-SNE to reduce the dimensionality of the data for visualization purposes. Once you have reduced the data to two dimensions you can easily replicate the visualization in the scikit-learn tutorial, see the code below for an example.
