Depth-first search

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…

scores triggered my English teacher’s arranging meeting with my parents and counselors to address my substandard skills. In short, after visited various specialists and many tests performed, amblyopia was the root cause of the inadequate development of my visual tracking, eye focusing, and eye teaming skills caused impediment in reading, copying from the board, taking notes, filling in scantrons, and maintaining concentration. Since the 7th grade, the school provided me with a 504 plan for my…

(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…

Oftentimes, it is first nature for a person to go about their daily life, paying more attention to the things they regard as failures and weaknesses. As humans who learn as we mature, we are not born with the innate ability to recognize all of the strengths that we actually possess and simply choose to overlook. Many of us, including myself, must first learn about our strengths from other sources, such as the StrengthsFinder assessment created by Donald O. Clifton, in order to realize and learn…

A). Perceiving objects in everyday aspects such as a living room with toys all over the floor, or a plate on the dining room table requires you to determine where the object begins and where it ends as you are measuring how much depth the item has (Gross, 167). You recognize the edges of each object as well as the belonging of each individual item to the tied environment. As infants grow up, they develop these abilities to be able to develop shadows to where the items edges are tied to the…

A skilled tattoo artist wouldn't dream of attempting to apply a shaded tattoo design without a tattoo machine. The tattoo machine uses a group of needles to automatically inject ink at the correct depth in the skin. The machine is connected to an electric motor that rapidly moves the needles up and down at a rate of 80 to 150 times per second. This rapid needle movement allows a shaded area of a tattoo design to be filled with ink quickly and evenly. Tattoo Tip #3 - Mix the tattoo ink. Tattoo…

five cradled ice cream cones, exuberantly embracing each other with sticky hands. Crisp pine trees lined the path through camp, framing the elated chaos. With a click, I stopped down the aperture, extending the depth of field and drawing each member of my wacky sixth grade group into focus. Hitting the shutter, I captured my composition of carefree elation. Although I created this image within a fraction of a second, the joyous frenzy it encapsulates took a week to compose. Fresh off the bus,…

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…
