This collection of Nuffield Maths resources explores Decision maths. The demand is roughly equivalent to that in GCE A level. They include slide shows to introduce the topics, student sheets and teacher notes, as well as other relevant resources. The teachers' notes start with a short overview of the activity, who and what it is designed for, and lists the necessary resources. The student sheets have background information where needed, and tasks for the students to work and reflect on.
Extensions and solutions are included in the teachers' notes. Then students to find an Eulerian trail for a network with four odd nodes. It involves students setting up their own network as the basis for a sightseeing tour. A cable TV problem introduces the topic and the rules for the two algorithms.
The students are then set a second problem involving a theme park. The tasks are based on decorating and furnishing a bedroom, and take students through the process of constructing an activity network and calculating the minimum completion time for the project.
The resources include slide shows to introduce the topics, student sheets and teacher notes, as well as other relevant resources.

Investigate the number of paths you can take from one vertex to another in these 3D shapes.Network Structure
Is it possible to take an odd number and an even number of paths to the same vertex? You can trace over all of the diagonals of a pentagon without lifting your pencil and without going over any more than once. Can the same thing be done with a hexagon or with a heptagon? Create your own networks. Can you draw one that is impossible to complete without lifting your pencil? Main menu Search.

Without taking your pencil off the paper or going over a line or passing through one of the points twice, can you follow each of the networks? If you are able to do this, mark your pathway and direction using arrows. To support this aim, members of the NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to embed rich mathematical tasks into everyday classroom practice.

Recently Passy visited Sydney in Australia, and found the rail network system to be far superior to that of Melbourne. This means that to get to many places we have to go into the City and then back out again. It also means that all trains have to go into the city loop and then back out again. Networks and Social Networking. The following video is an excellent introduction to Networks, including an overview of Social Networks.
Mathematical Components of a Network. Note that we have coloured in the Regions; however network diagrams are not usually coloured in like this. Note that Edges can be straight lines or curves. If the equation does not work out equal on both sides for a Network, then one of our counts of the Vertices, Edges, or Regions must be incorrect, and we need to go back and check through our work.
Answers to Examples. Tree Diagram Network. A tree diagram is a special type of open network. This Network has only one Region, but many Vertices and Edges. Each vertex connects to one or more other Vertices, making the Network branch out into more and more paths that can be taken from the original starting point.
Tree Diagrams are useful for organising tasks, and classifying situations into groupings. They are also used for breaking down complex items into sub-groups of simpler items.
Colouring in Networks. The rule for colouring in such diagrams is that two adjoining Regions next to each other must not be shaded in the same colour.
Not every region has to be a different colour, but we need to make sure we separate regions using colours, and do not have two regions next to each other as the exact same colour.
This first example is incorrect, because the two middle states have been coloured in the same red colour. This makes it appear as though they are one region instead of two separate regions.
The next example shown below is correct, where all regions can be seen as being separate from each other. It does not matter that we have used the colour pink for two separate regions, because they do not touch each other on the map. If we were asked to colour the map in using the least number of colours possible, then the following would be one of several possible correct solutions that use only four colours.
A flow must satisfy the restriction that the amount of flow into a node or Vertex equals the amount of flow out of it, except when it is a source, which has more outgoing flow, or a sink, which has more incoming flow. A flow network can be used to model traffic in a road system, fluids in pipes, currents in an electrical circuit, or anything similar in which something travels through a network of nodes.
Networks and Traffic Flow. In the following video, Dr. Chris Bishop explains an interesting paradox that shows how the removal of very fast roads, like removing a tunnel through the middle of a citycan actually reduce average journey times. Additional Information. There is a great introduction to Network Mathematics written by Bruce Hoppe at the following web page:.

Would you like to tell us about a lower price? This book introduces the reader to the basic math used for neural network calculation. This book assumes the reader has only knowledge of college algebra and computer programming. This book begins by showing how to calculate output of a neural network and moves on to more advanced training methods such as backpropagation, resilient propagation and Levenberg Marquardt optimization.
The mathematics needed by these techniques is also introduced. Mathematical topics covered by this book include first, second, Hessian matrices, gradient descent and partial derivatives.
All mathematical notation introduced is explained. Neural networks covered include the feedforward neural network and the self organizing map.
This book provides an ideal supplement to our other neural books. This book is ideal for the reader, without a formal mathematical background, that seeks a more mathematical description of neural networks. Read more Read less. Kindle Cloud Reader Read instantly in your browser.

Its freshman calculus and applied math rolled together in a developing brew.
This introduction is gentle and it will all make sense if you buy another few books on the subject. However, this is not a one stop shop for neural network design. The book is more a basic presentation of various mathematical tools that can be applied to neural networks. The book requires the reader to have familiarity with basic calculus and derivatives. Otherwise it's a walk in the park. After all, you are going to have to stretch a bit to benefit from this knowledge, so the effort is worth it.
The title does say that this is an introduction, so don't be too disappointed that everything isn't laid out for you. There is no effort to categorize the functions introduced or to produce an overall design process of selection appropriate for a particular task. That information comes from further study in this area.Co-authorship network map of physicians publishing on hepatitis C.
