Introduction to Genetic Algorithms — Including Example Code

A genetic algorithm is a search heuristic that is inspired by Charles Darwin’s theory of natural evolution. This algorithm reflects the process of natural selection where the fittest individuals are selected for reproduction in order to produce offspring of the next generation.

Notion of Natural Selection
The process of natural selection starts with the selection of fittest individuals from a population. They produce offspring which inherit the characteristics of the parents and will be added to the next generation. If parents have better fitness, their offspring will be better than parents and have a better chance at surviving. This process keeps on iterating and at the end, a generation with the fittest individuals will be found.
This notion can be applied for a search problem. We consider a set of solutions for a problem and select the set of best ones out of them.
Five phases are considered in a genetic algorithm.
Initial population
Fitness function
Selection
Crossover
Mutation
Initial Population
The process begins with a set of individuals which is called a Population. Each individual is a solution to the problem you want to solve.
An individual is characterized by a set of parameters (variables) known as Genes. Genes are joined into a string to form a Chromosome (solution).
In a genetic algorithm, the set of genes of an individual is represented using a string, in terms of an alphabet. Usually, binary values are used (string of 1s and 0s). We say that we encode the genes in a chromosome.

1 poin
pheromones are secreted by the thyroid and produce insulin
pheromones are released into the environment rather than being held within the body
tissues
female pheromones tell males which females have compatible immune systems
O none of the above statements are true
The correct answer is B. Pheromones are released into the environment rather than being held within the body.
Explanation
Pheromones are chemical substances secreted by living beings, in order to cause specific behaviors in other individuals of the same species. They are a means of transmitting volatile signals produced in liquid form, which are then dispersed throughout the environment. This is used by different species of plants and animals as a means of communication and almost all send one or more codes by this means, both to attract or reject each other sexually as well as for other purposes. According to the above, the correct answer is B. Pheromones are released into the environment rather tan being held within the body.

What is grieving?Grief is a natural and normal reaction to loss. Though we usually expect to be saddened by the loss of a family member or companion, many other massive losses can cause grief. Here are some examples: The breakdown of a relationship.
Grief has a variety of physiological effects, including inflammatory processes, joint pain, fatigue, and digestive issues.
It can also reduce your immunity, making you more prone to illness. Grief can also lead to cardiovascular problems, insomnia, and unhealthy coping mechanisms.
Depression is typically the most difficult and prolonged stage of grief.
As Brandon's grandfather died 8 months ago, he is sad much of the time and has not rejoined his favorite activities. This implies that he may be suffering from abnormal grieving.
Thus, the correct option is C.
