[gecode-users] How to find my problem?
Gilberto Cuba Ricardo
gcubar2005 at gmail.com
Wed Dec 3 18:59:09 CET 2014
Hi Tommaso,
You give me a insight. When a node is stable? I suspect that I have this
kind of problem; because when I run the application its return quickly that
not have solution. My Space is not configured with
GECODE::Search::TimeStop, to return a quick response that there is no
solution. I have other restrictions that take more time for response, and
as I have set them a reasonable stop time to 1s, these returnees have no
solution.
I followed the suggestion of Guido, and I rationally targeted restrictions
that create the problem under certain conditions. However, not
able to determine the real sense of it.
Is there any validation on engine to return quickly not have solution?
Thanks.

Preface
Recent advances in 3D visualization and physics-based simulation technology, at both the software and hardware levels, have enabled game developers to create compelling, visually immersive gaming environments. The next step in creating even more immersive games is improved artificial intelligence (AI). Advances in computing power, and in hardware-accelerated graphics in particular, are helping to free up more CPU cycles that can be devoted to more sophisticated AI engines for games. Further, the large number of resources—academic papers, books, game industry articles, and web sites—devoted to AI are helping to put advanced AI techniques within the grasp of every game developer, not just those professionals who devote their careers to AI.
With that said, wading through volumes of technical papers, text books, and web sites can be a daunting task for upcoming game AI developers. This book pulls together the information novices need so that they can get a jump-start in the field of game AI development. We present relevant theory on a wide range of topics, which we support with code samples throughout the book.
Many general game development books cover AI to some extent, however their treatment of the technology tends to be limited. This is probably because such books have to cover a lot of different topics and cannot go into great depth on any particular one. Although several very good books do focus on game AI (we list many of them in the "Additional Resources" section of this Preface), most of them are geared toward experienced AI developers and they focus on relatively specific and advanced topics. Therefore, novices likely would require companion resources that cover some of the more fundamental aspects of game AI in more detail. Still other books cover some specific game AI techniques in great detail, but are restricted to covering just those techniques.
Our book covers a wide range of game AI topics at a level appropriate for novice developers. So, if you are new to game programming or if you are an experienced game programmer who needs to get up to speed quickly on AI techniques such as finite state machines, fuzzy logic, and neural networks, among others, this book is for you.

Starting with Tensorflow
import tensorflow as tf
a = tf.constant("Hello World !!")
sess = tf.Session()
print sess.run(a)
What is TensorFlow
Tensorflow is an interface for expressing machine learning algorithms and an implementation for executing such algorithms
A computation expressed using Tensorflow can be executed with little or no change on a wide variety of heterogeneous systems
Deep Learning Tools
- Theano, Tensorflow
- Python as programming interface
- Tensorflow has better support for distributed systems
- Tensorflow is one of the popular project on github.
- Torch
- Lua as programming interface
- Caffe, CNTK
- C++ as main programming interface
- Comparision with other tools can be found on Wikipedia
TensorFlow Computation Graph
Computation is described as directed graph
Edges represents data flow node represents operations
Provides extensions to support looping control on graph, maintaing state etc
computations graph are constructed using C++/Python programming interface
TensorFlow Operations
Operations represents abstract computation (matrix multiplication, add)
Operations are polymorphic over different tensor elements
Device specific kernels executes the operations
Tensorflow Programming Model
Construction phase which assembles the graph
Execution phase that uses session to run the operations on the graph
TensorFlow Session Object
A session object encapsulates the environment in which Operation objects are executed and Tensor objects are evaualted.
A session may own resources, such as variables, queues, and readers. It is important to release these resources when they are no longer required. To do this, either invoke the close() method on the session, or use the session as a context manager
