    Best-First Search Paper

    Beam search is an informed algorithm for searching a graph that extends the Breadth-First search (Jungwirth, 2006). The Breadth-First search is essentially a special-case Best-First search where the evaluation function, f(n) is the same as the heuristics function, h(n) (JONES, 2008). Therefore in order to properly discuss Beam search, there is the need for a brief introduction to Best-First algorithm. The Best-First search traverses a tree from top to bottom and searches for nodes on the same level first before descending to the next level. Nodes on the search frontier (nodes on the same level) are selected based on some evaluating function that is defined depending on the nature of the problem (heuristics function) and the estimated cost. The evaluating function f(n) is therefore the sum of the heuristic function h(n) and the estimated cost g(n). This algorithm is complete as it will always find the solution if it exists but it not optimal as it might find a solution of longer length depending on the heuristic function applied. The time and space complexity is both O(bm) where b is the branching factor and m is the tree depth.…

    of the sculpture by observing all angles. The way the viewer sees it in my opinion is how capable they are to understand the interaction of the parallel lines and the three-dimensional forms in his artwork. The artist used the elements of art in his artwork by including the environment because this allows the viewer to see an ordinary art into something more pleasurable and functional by providing different focal points. In other words, a simple piece of art can have different functions…

    1. ABSTRACT The essence of an image is a projection from a 3D scene onto a 2D plane, during which the depth information is lost. The 3D point corresponding to a specific image point is constrained to be on the line of sight. From a single image, it is very difficult to determine the depth information of various object points in an image. If two or more 2D images are used, then the relative depth point of the image points can be calculated which can be further used to reconstruct the 3D image by…

    minor details either. It is quite possible this is due to the fact that cataracts create strange warped and blurred areas within the eye lens, so these warped brush strokes are most likely a result of that blurriness. Shapes within the work are all very warped and fluid. They almost appear as if monet was painting the scene viewed through a glass of water, an apt comparison for what having a cataract can be like. Even the bridge depicted in the center of the painting is warped and squiggly. The…

    Art work, despite the medium, embraces numerous visual elements that give birth to a finished work of art; such components include, but are not limited to: line, space, light and color. These elements are the building blocks that create masterful pieces while concurrently breaking down the meaning of the work in question. In relation to Learoyd’s, Andrew on Plinth, the formal elements of space and light are predominant. Notably, Learoyd’s piece depicts space in a few ways. First, notice the box…

    (NAAION), I realized that I undeniably take completing my activities of daily living for granted. This experience has made me appreciate my capabilities more. Focusing in class, studying, and grocery shopping were some activities that I had the greatest difficulty with. Overall, I learned how to be more empathetic towards individuals who are actually affected by this disability by placing myself in their shoes. Upon waking up on Tuesday morning, I immediately covered my left eye with an…

    perceive depth once again this is going to be different for everyone and every eye. This essay will reflect on many of my own thoughts and questions that pertain to this chapter. To begin with I find it interesting that ciliary muscles in and around our eye help to determine our depth. Other cues that exist determine our depth is the monocular and binocular cues. I find these two cues difficult to understand. What exactly is a monocular cue? What exactly is the binocular cue? I understand that…

    Critical period plasticity vs Plasticity throughout life In neuroscience they mention that there is two types of plasticity during our lifetime, critical period plasticity being the first during our postnatal development, then comes plasticity. Critical period plasticity is a particular time frame in which the brain development is sensitive to a certain experience such as vision, and once the critical period ends there is no more plasticity occurring (Kolb and Whishaw, 270). On the contrary…

    itself. 2. a) Explain the importance of depth perception, and b) discuss the contribution of visual cliff research to our understanding of this ability. The importance of depth perception is that it helps us determine how far an object is from us. For instance, when a person is driving on the road they use depth perception to estimate how far they are from their destination. The contribution of visual cliff research to our understanding of this ability is that this experiment allowed people…

    In Chapter 10, Perceiving Depth and Size it talks about the way you look at things from far and near.

Well, this chapter gives you information on this question. They are three cue approach to depth perception, they are oculomotor cues, monocular cues, and binocular.
