Best-first search is a search algorithm which explores a graph by expanding the most promising node chosen according to a specified rule.
Judea Pearl described best-first search as estimating the promise of node n by a "heuristic evaluation function
f
(
n
)
{\displaystyle f(n)}
which, in general, may depend on the description of n, the description of the goal, the information gathered by the search up to that point, and most important, on any extra knowledge about the problem domain."Some authors have used "best-first search" to refer specifically to a search with a heuristic that attempts to predict how close the end of a path is to a solution (or, goal), so that paths which are judged to be closer to a solution (or, goal) are extended first. This specific type of search is called greedy best-first search or pure heuristic search.Efficient selection of the current best candidate for extension is typically implemented using a priority queue.
The A* search algorithm is an example of a best-first search algorithm, as is B*. Best-first algorithms are often used for path finding in combinatorial search. Neither A* nor B* is a greedy best-first search, as they incorporate the distance from the start in addition to estimated distances to the goal.
Objectives:
- best path for optics needed to focus and "draw"/project a high resolution image onto a workspace around 500mm square (for a Laser Direct Imaging machine)
- where to cost effectively purchase or make the optics necessary to build a prototype
The problem:
I need to project a high...
Ho. Which is the best Path to study math & physics? I have Larson Calculus and Halliday Fundamentals of physics. I have know some algebra. No geometry and trigonometry :(
Thanks.
Hello,
I was just curious about what academic education is the best to get into statistical physics, and more specifically the statistical physics of optics and lasers. I have considered a few possibilities.
Getting a PhD in statistics but take physics electives and most physics courses that...
Guys I have the following homework problem to solve:
There are 2 given points in a plane. If we take a point-like object with mass m and take it to the "higher" point what path should it go on to reach the other point in the shortest possible time. Only gravitational force affects our point-like...
Hello All,
I only have a vary basic understanding of physical concepts so please bear with me.
I'm an object with mass greater than 0, a maximum speed, a maximum rate of acceleration and deceleration.
Suppose I want to travel from point A to point B. The path is chosen for me and it leads...
Hi guys. It's my first post here so I am not sure how this works but I'll give it a try. So I'm a senior in high school and I'm trying to progress my way up to learning QFT. I was wondering what I should do next in my series of things to learn. So far, I've learned the following:
1. Regular...
I'm new to this forum, and would just like to say this is a very impressive site. My question is what is the best path way in school to design heat exchangers for power plants (more geared towards nuclear power plants.)
I'm currently finishing my first year of school studying mechanical...
I am a senior right now in high school and am pretty much deciding the beginning of the rest of my career right now. Ultimately, I would love to study both physics and computer science with either a double major or with computational physics. I love learning about mathematics, physics, computer...
Hi,
I think some background is necessary:
I'm a Psychology undergraduate student. I also really love math. I've incorporated some pure math into my studies - next semester I'll have room for a course on "Foundational Mathematics" (I'm not sure if that's exactly what they call it outside my...
I have a BS in Mechanical Engineering and I've been out of school for almost 5 years. Several months back I started learning Java just for kicks, but I've reached a point where I'm pursuing more and more knowledge of CS concepts on my own, and the interested level is far exceeding that of...
Hello folks!
How can we find the best path to drive in a circuit in order to do the best lap time? :)
I've been trying to solve this problem for 2 weeks, trying to find some functional to minimize, but I'm stuck!
Little help? :)
P.S.
This is not homework :) I just want to know how to beat...
Ok. Ill give some info about myself, and what I have accomplished, and how the past year and a half has been horrible for my grades(and general academic career)
Largely on my own, I studied algebra in the fifth grade. I was able to take algebra as an official class in the sixth. In that...
First, I believe I should mention that I have almost no idea how admissions to grad school works or of how grad school works in general.
Basically, I want to know what I should do to get into the best Grad school in the future. When I got to college, I had wished that I had begun preparing...
I currently have a bachelors in nuclear engineering and work for a utility company. For my career I would like to eventually get my masters and Ph.D and go on to work in research, at a university or national lab. What would be the best course of action for me? My job will reimburse me for...
I'm about to start my 3rd year in physics at Oxford, and I want to do a theory Phd eventually. Unfortunately though, I don't think that the fourth year at Oxford is very good for aspiring theoreticians (there are no courses in string theory, QFT etc. the particle physics option is experimentally...
