For example, all cells in the same row, column or block will have edges between their corresponding vertices. If (Degree(graph.Nodes) > Degree(graph.Nodes))ĪssignColor(graph.Nodes, nodeSet, ref colorNumber) Ī Sudoku puzzle (9x9) can be thought of a graph with 81 vertices, one for each cell, and two vertices are connected by an edge if they cannot be assigned the same value. Int colorNumber = 1 // number of used colors int numberOfColoredNodes = 0 The vertices are ordered according to their saturation degree and if two vertices have the same degree the tie is broken by comparing their degree. The saturation degree of a vertex is the number of its adjacent differently colored vertices. The proposed algorithm uses a combination of saturated degree ordering (SDO) and degree ordering that we explained earlier. Hussein Al-Omari and Khair Eddin Sabri published in the American Journal of Mathematics and Statistics.Īs I discussed earlier, the trick is choosing the next vertex to color. In my implementation, I choose a greedy coloring algorithm with some modifications as proposed in the paper by Dr. Now, the vertex with maximum degree is ( each group will take a different color. Hence, Vertex (1) and (4) are contracted into one node. Let’s go back to our example. Vertex (1) has the maximum degree its non adjacent vertices are vertex (4). Repeat steps 1-6 until the resulting graph has all contracted nodes adjacent to each other. Remove Y from the set and repeat steps 3-5 until the list is empty.ħ. Contract Y into V to be colored with the same color.ĥ. From this set select the vertex Y of maximum common vertices with V.Ĥ. Find the set of non-adjacent vertices to V.ģ. A contraction algorithm would work as follows:ġ. The second category “Contraction” works by finding two vertices removing any edges between them, and replacing them with a single vertex where any edges that were connected to any of them are now redirected to new single vertex. Now the graph looks like this and we are left with one vertex which will be colored green. Now the graph looks like this and the new list is 5, 3,2ĭon’t color blue because it is connected to 5 Remove colored vertices from the list and repeat the process until all vertices are colored.ĭon’t color red because it is connected to 1 Go through the list, color each vertex not connected to colored vertices with the same color.Ĥ. Order the vertices in descending order according to their degree.ģ. (Degree: is the number of edges connected to it)Ģ. Algorithms under this category differ in the way the next vertex is selected.Ī famous algorithm under this category is the Welsh–Powell algorithm. Once a vertex is colored, its color never changes. Greedy Coloring focuses on carefully picking the next vertex to be colored. Most of the algorithms can be broadly categorized in one of two main topics “Contraction” and “Greedy Coloring”. Graph coloring is computationally hard and it has been a research topic for many years. Contraction and Greedy Coloring Algorithms Therefore, the smallest number of colors needed to color a graph is called its chromatic number. If you tried to color the above graph using only two colors you will find out that it cannot be colored at all, Go try it out I will wait :). coloring (1) in the above example is a 3-coloring while coloring (2) is a 5-coloring). A coloring that uses at most k colors is called k-coloring (e.g. Our color is to find a coloring of a given graph that uses the minimum number of colors. Coloring (1) uses the 3 colors while Coloring (2) uses 5 colors, hence, coloring (1) is better than coloring (2). Below are another two possible colorings for the example graph. The goal is to use the minimum number of colors possible. It should be clear by now that one graph can have more than one possible coloring. Below is one possible coloring of this graph. However, vertices 2 and 3 can have the same color because they are not connected. For example, in the graph mentioned above vertices 1 and 2 cannot have the same color because they have an edge connecting them. Graph coloring is the assignment of "colors" to vertices of the graph such that no two adjacent vertices share the same color. The objects are represented by vertices (nodes) and the links are called edges. Graph Coloring DemystifiedĪ graph is a mathematical representation of a set of objects where some pairs of objects are connected (linked) to each other. This article assumes that the reader is already familiar with the concept of a graph and its representation. In this article, I will explain the concept of graph coloring and how it can be used to solve a 9x9 Sudoku Puzzle.

It is also bolstering efforts in the US and the Middle East, and executives said in August the business was approaching break-even.Īlibaba has highlighted trillions of dollars in Chinese household savings as a key driver of growth, with the company pledging to continue investing in expansion even if it drags down earnings in the short term.

The venture by the Hangzhou-based company would be powered by its cloud computing business, where revenue surged by 156 percent in the June quarter. “Retail stores can directly place orders online with the brands.” “Why do brands need so many layers of distributors?” said Zhang. That data then would be used to adjust inventories more quickly in response to demand, an undertaking that now requires several layers of reporting between the store and the brand.

Then, the transcriptionist can go back and listen to the audio recording and make edits to ensure maximum accuracy. Some medical transcriptionists may use speech-to-text software to create an initial draft of the audio recording. The foot pedal is a standard transcriptionist tool that allows an individual to fast forward, rewind, slow down, or speed up the audio recording while typing. Medical transcriptionists use tools like a headset, computer, keyboard, and foot pedal to type and record the audio files quickly. Accurate transcription is essential for medical transcription jobs because hospitals, medical facilities, and doctors rely on these patient files and notes to treat and diagnose their patients later on. While listening to the audio file, the transcriptionist will type the audio into text quickly and accurately. What does a medical transcriptionist do?Ī medical transcriptionist, also known as a medical scribe, is a job that requires an individual to listen to audio recordings from doctors, nurses, or other healthcare professionals. So, if you’re interested in helping others, working from home, and making money while you do it, how can you get started? Today, we will cover everything you need to know about how to become a medical transcriptionist. These notes and patient files must be accurate so that doctors, hospitals, and other medical facilities have correct notes on their patients to refer back to. Medical transcriptionists type up notes and patient files from audio files created by doctors, nurses, and other medical professionals. Not only can most medical transcriptionists work from home or remotely, but they can help others while they do.

Hades is possibly the exception, as articles revealed his surname is Polydegmon or “the one who receives many,” a little similar to his popular epithet. Norse deities have “-son (son of)” or “-dottir (daughter of)” in theirs, Greek and Roman gods don’t. There’s an online debate whether deities have surnames. Read also: 15 Facts About Bob Sapp Hades bears the surname Polydegmon. His alternative names Zeus Eubuleus (good counsel) and Zeus Meilichios (easy-to-be-entreated) came from Orphic hymns and he both Hades’ alternative names. This is probably the reason why Hades was sometimes called “the second Zeus.” Hades is just as powerful as his brothers, but his youngest brother took the title of being the chief Olympian god. Some of his alternative names start with Zeus. Some of his other epithets are Plouton (the rich one), Clymenus (notorious), and Hesperos Theos (god of death and darkness). It’s not a surprise that the epithet “god of wealth” fits Hades since everything within his realm is his. Though the Earth is abundant with wealth, there’s a lot more undiscovered underneath it. Photo from: Wikimedia Commons His most popular epithet is the “god of wealth.” The most common meaning behind his name is “the unseen one,” and in some translations “his knowledge of all noble things.”īritish classical scholar Martin Litchfield West argued that the name Hades’ original meaning is “the one who presides over death,” a fitting name for the god of the Underworld. His name means many things, whether it comes with the job or not. Hades means “the one who presides over death.” 12/9/2023 0 Comments Malwarebytes rulesWe advise against blocking the technology content category as most of the domains for My Account and e-commerce activity are included in that category.
