A* is a heuristic path searching graph algorithm. This means that given a weighed graph, it outputs the shortest path between two given nodes.
The algorithm is guaranteed to terminate for finite graphs with non-negative edge weights. Additionally, if you manage to ensure certain properties when designing your heuristic
Variables are named memory locations. Their values are saved in memory, which we can't typically remember as they're not human-friendly and shift around. Though, if we name the memory location, such as a, it's a lot easier to remember.
Environment variables are a lot like usual programming variables, except
Reading user input is the first step towards writing useful Java software. User input can come in many forms - mouse and keyboard interactions, a network request, command-line arguments, files that are updated with data relevant for a program's execution, etc.
We're going to focus on keyboard input via
This is the second article in a short series dedicated to Design Patterns in Python.
Structural Design Patterns are used to assemble multiple classes into bigger working structures.
Sometimes interfaces for working with multiple objects simply don't fit, or you're working with legacy code you can't
This is the first article in a short series dedicated to Design Patterns in Python.
Creational Design Patterns, as the name implies, deal with the creation of classes or objects.
They serve to abstract away the specifics of classes so that we'd be less dependent on
Design Patterns are reusable models for solving known and common problems in software architecture.
They're best described as templates for dealing with a certain usual situation. An architect might have a template for designing certain kinds of door-frames which he fits into many of his projects, and a software
Design principles are generalized pieces of advice or proven good coding practices that are used as rules of thumb when making design choices.
They're a similar concept to design patterns, the main difference being that design principles are more abstract and generalized. They are high-level pieces of advice, often
Genetic algorithms are a part of a family of algorithms for global optimization called Evolutionary Computation, which is comprised of artificial intelligence metaheuristics with randomization inspired by biology.
In the previous article, Introduction to Genetic Algorithms in Java, we've covered the terminology and theory behind all of the things
