Design patterns are a means to communicate, identify, and remember solutions to common problems. Each pattern names, explains, and evaluates a solution to a common problem. Each design pattern has four essential elements: Behavioral, Creational and Structural Diagram.
Design patterns have 4 essential elements:
In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn't a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations.
Object Oriented Programming is itself a design pattern. Design Patterns are common approaches to solving problems that come up on OOP programming. ... Using normal OOP techniques, one would make an interface or virtual methods that each class implements.
Following the SOLID acronym, they are:

There are mainly three types of design patterns:

Three Types of Design Patterns(Behavioral, Creational, Structural) Distinguish between Behavioral, Creational, and Structural Design Patterns.

There's no one right answer for when a particular design or design pattern should be used, you need to build up experience in using and implementing them in order to know when and where to use which pattern. Experience. Learn the patterns and real-world examples of their uses.
A pattern is a regularity in the world, in human-made design, or in abstract ideas. As such, the elements of a pattern repeat in a predictable manner. A geometric pattern is a kind of pattern formed of geometric shapes and typically repeated like a wallpaper design. Any of the senses may directly observe patterns.
Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically. Natural patterns include symmetries, trees, spirals, meanders, waves, foams, tessellations, cracks and stripes.
The definition of a pattern is someone or something used as a model to make a copy, a design, or an expected action. An example of a pattern is the paper sections a seamstress uses to make a dress; a dress pattern. An example of a pattern is polka dots. An example of a pattern is rush hour traffic; a traffic pattern.
A pattern can be called a pattern only if it has been applied to a real world solution at least three times.
(Actually, the person I learned that from said “Third time is enemy action”.
A pattern can be formally defined as a noticeable regularity in the natural and man-made world that repeats itself in a predictable manner. ... Man-made patterns are often used in design and can be abstract, such as those used in mathematics, science, and language.
The Core The part of a repeating pattern, that stays the same and repeats itself, is called its core.
Pattern is a combination of elements that are repeated....We can use five types of rhythm:
Increasing patterns are patterns in which one or more elements of the sequence or arrangement increases. Increasing patterns should be both numerical and non- numerical.
There are two really easy ways to develop pattern recognition skills:
The main types of data patterns are level or horizontal, trend, seasonality and cycles.
A pattern is a series of data that repeats in a recognizable way. It can be identified in the history of the asset being evaluated or other assets with similar characteristics. Patterns often include the study of sale volume, as well as price.
Recognizing patterns allows us to predict and expect what is coming. The process of pattern recognition involves matching the information received with the information already stored in the brain. Making the connection between memories and information perceived is a step of pattern recognition called identification.
Humans have a tendency to see patterns everywhere. That's important when making decisions and judgments and acquiring knowledge; we tend to be uneasy with chaos and chance (Gilovich, 1991). Unfortunately, that same tendency to see patterns in everything can lead to seeing things that don't exist.

Branching pattern is defined by branch order or its position in the hierarchy of tributaries. ... In a forest ecosystem, the shrubs do not show large difference in gross branching structure (ratio of terminal to supporting branches).
Release Branches. Most software has a typical life cycle: code, test, release, repeat. There are two problems with this process. First, developers need to keep writing new features while quality assurance teams take time to test supposedly stable versions of the software.
Cymose branching: The terminal bud stops its activity, further growth is continued by a single axillary branch. They are of three types namely, uniparous cymose, biparous cymose and multiparous cymose.
Monopodial branching occurs when the terminal bud continues to grow as a central leader shoot and the lateral branches remain subordinate—e.g., beech trees (Fagus; Fagaceae). Sympodial branching occurs when the terminal bud ceases to grow (usually because a terminal flower has formed) and an axillary…
