greedy algorithm

by: Jack Smith |last post by:

Hello, any help appreciated with following problem. I figured out the algorithm (I think), just having trouble proving it is optimal. Suppose we are given n tasks each of which takes 1 unit time to complete. Suppose further that each task has a deadline by which it is expected to finish. IF a task is not finished by the deadline, a standard penalty of $10 is applied. The problem is to find a schedule of the tasks that minimizes the...

YARD : Generic regular expression parser

by: christopher diggins |last post by:

There seems to be a gazillion regular expression libraries. Most of them only work on text, but I wanted something that also worked on arbitrary sequences of data ( this is useful, for instance, in building parse trees from token lists ). This is possible, I think, using the Spirit library from Boost, but the syntax and complexity again is too much for me. I almost finished the YARD ( yet another recursive descent ) parser which is a really...

Prime number algorithm in C

by: Cmorriskuerten |last post by:

HI, is this is this solution to test if a number is a prime number or not: /* * Is n a prime number? * Return TRUE (1): n is a prime number * Return FALSE (0): n is a *not* a prime number */ int is_prime_number(int n)

How good an encryption algorithm is this?

by: Bonj |last post by:

I was in need of an encryption algorithm to the following requirements: 1) Must be capable of encrypting strings to a byte array, and decyrpting back again to the same string 2) Must have the same algorithm work with strings that may or may not be unicode 3) Number of bytes back must either be <= number of _TCHARs in * sizeof(_TCHAR), or the relation between output size and input size can be calculated simply. Has to take into account the...

Problem with sorting algorithm and double linked lists

by: FBM |last post by:

Hi, I am working on a program that simulates one of the elements of ATM. The simulation stores events which occurs every some milliseconds for a certain amount of time. Every time that an event is stored in a double linked list, the whole list is sorted for the next round. My problem appears when subjecting the program to heavy load, that is, when I run the simulation for more than 10,000 miliseconds (every event occurs in...

New lightweight block cipher algorithm

by: Julio C. Hernandez Castro |last post by:

Dear all, We have just developped a new block cipher called Raiden, following a Feistel Network structure by means of genetic programming. Our intention now consists on getting as much feedback as possible from users, so we encourage you to test the algorithm and send us your opinion. We would also like to receive enhancements and new versions of the algorithm, developed in other source languages and platforms. Our idea on developing...

float encoding algorithm

Changing the language in Windows 10

by: Hystou |last post by:

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it. First, let's disable language synchronization. With a Microsoft account, language settings sync across devices. To prevent any complications,...

Problem With Comparison Operator <=> in G++

by: Oralloy |last post by:

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

The easy way to turn off automatic updates for Windows 10/11

by: Hystou |last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Discussion: How does Zigbee compare with other wireless protocols in smart home applications?

by: tracyyun |last post by:

Dear forum friends, With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...
