c++ stl nfa automaton 2013-12-18 12:51:27
For some days I’m trying to do a program for simulate a nondeterministic finite automaton (NFA), more specifically, a string recognizer. After several failures, thanks to the user Konrad Rudolph, I could implement a solution based on this pseudocode:Well, in an NFA you have a set of current states, and in each step you go through all current states, and for each, you select all valid transitions. Those combined sets form your new state set.At the end, you check whether the intersection of the cu

I have some code which I adapted (barely changing it) from the C++ Concurrency In Action book, so would have expected it to work — only it doesn’t. What I’ve tried to do is to implement a thread-safe queue that I can then store background jobs for a thread or threads in. The queue looks like this:queue.h#pragma once #include “imgproc/i_queue.h” #include <memory> #include <thread> #include <queue> #include <mutex> #include <condition_variable>using namespace std;nam

I am trying to troubleshoot a project that uses openCV. Somewhere, there is a histogram equalization – that crashes when the input image is pure black (or pure white or pure something).I have been trying to troubleshoot the debug assertion failure that I get – “Expression: vector subscript out of range” – unsuccessfully. Note: the method does not use EqualizeHistogram, it creates the histogram manually, counts pixels per level, does an average – like in the textbook. If I can isolate the case wh

My problem is that sometimes, when closing the game, one of two may occur:Process stays in memory and it have to be killed manually Game crashesI’m not sure if those two are related or completely independent issues. Both of those happen very rarely, but I have to eliminate these situations.As for the crash, I made a dump and it says that the crash occurs in PeekMessage() function. The code looks like this:bool running = true;/// Reset timer Timer.Reset();MSG msg; ZeroMemory(&msg, sizeof(msg)

Is possible to recover the exact values of argv and argc parameters of a main after the application crashed?I need to use only the application core-dump and gdb debugger on Linux.

When,i try to assign null value to my pointer,it sometimes crashes on that line. The code is something like this :if(s_counter != NULL) {delete s_counter;s_counter = NULL; // it sometimes crashes here. }This is not reproducable,100%,but it occurs frequently. Can anybody help in this?

I’m trying to debug a crash in a full-screen Mac game I’m working on, but when I have LLDB attached it just causes the game to freeze when the crash happens, and I can’t get away from the game – I need to do a hard reset on the computer. Is there any kind of tool or preference for doing this? The computer I’m using to reproduce the crash doesn’t have multiple monitors.

I have a program that launches a child process. When the child process crashes I would like there not to be a debug message box. I would like to do this without writing anything in the child process.I am running this on windows 7.In the createProcess function, in the flags parameter I only put CREATE_NEW_CONSOLE.During my attempts, I put SetErrorMode(SEM_FAILCRITICALERRORS|SEM_NOGPFAULTERRORBOX) in the child process and made it crash, there was no dialog box. Now I put the same function call in

[Edit] When I try Sumant’s suggestion of switching out “v.getContext()” with “this” in the Intent constructor Eclipse says it can’t build the app. When the onClick() method is called isn’t the current View passed to it?[Edit 2] I may have figured out the problem. It could have been that I was using a layout meant for Android 3.0 when I was using an Android 2.3.3 emulator. It was either that, or my just using a string array rather than an integer array.In my Android app when a user clicks on a

I’ve posted a similar question to here: why it crashes when assigning new values to arrays?But this time, I encountered another problem with arrays again. My code is like this: double diff[600][800][3]; cv::Mat value ( height, width, CV_8UC3 ); double mean[600][800][3]; …. for ( int i =0; i < 5; ++ i ) {for ( int j = 0; j < 3; ++j ){for ( int m = 0; m < 2; ++m ){mean[i][j][m] = 10/m;diff[i][j][m] = abs ( value.data[value.cols*i+j]-mean[i][j][m]);}} }It crashed at the line:diff[i][j][m

First off, i’ll say thank you in advance for any help you can give. I know this is my first post, and it’s going to be a little dense, so I’ll apologize for that straightaway. Here goes. So this program is supposed to be a sort of dumb database that uses a hash-table for storing a ‘person’ struct that is constructed from a file. Each ‘person’ in the database has a certain number of hours volunteered, and based on how many hours they volunteered, they owe a certain amount of money. (more voluntee

I’ve got a crash happening on my node server and I can’t figure out how it could logically happen. I haven’t personally repro’d but its happened a few times in the last week according to bugsnag. Any thoughts on why it might be happening or suggestions for additional logging to help debug would be greatly appreciated.I’ve got a 2-player game, where each person is dealt a hand, and then needs to select two cards from their hand to discard. Discarding is done simultaneously, so players may discard
