Inclusive Fitness00:57

Inclusive Fitness

35.9K
Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

Altruism01:03

Altruism

41.0K
Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.

Mechanistic Models: Compartment Models in Algorithms for Numerical Problem Solving

45
Mechanistic models play a crucial role in algorithms for numerical problem-solving, particularly in nonlinear mixed effects modeling (NMEM). These models aim to minimize specific objective functions by evaluating various parameter estimates, leading to the development of systematic algorithms. In some cases, linearization techniques approximate the model using linear equations.
In individual population analyses, different algorithms are employed, such as Cauchy's method, which uses a...

What is Behavior?00:54

What is Behavior?

8.9K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Predator-Prey Interactions02:39

Predator-Prey Interactions

16.1K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Evolutionary Psychology01:20

Evolutionary Psychology

255
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

Two new bio-inspired particle swarm optimisation (PSO) algorithms, BEPSO and AHPSO, leverage natural group behaviors to enhance swarm diversity and prevent premature convergence. Both algorithms demonstrate competitive performance on complex optimization problems.

Area of Science:

  • Computational Intelligence
  • Optimization Algorithms
  • Bio-inspired Computing

Background:

  • Particle Swarm Optimization (PSO) is a metaheuristic inspired by social-insect behavior.
  • Maintaining swarm diversity is crucial for preventing premature convergence in PSO algorithms.
  • Novel bio-inspired mechanisms can potentially improve the performance of existing optimization techniques.

Purpose of the Study:

  • To introduce two novel bio-inspired Particle Swarm Optimization (PSO) variants: Biased Eavesdropping PSO (BEPSO) and Altruistic Heterogeneous PSO (AHPSO).
  • To investigate the effectiveness of these new algorithms in maintaining swarm diversity and preventing premature convergence.
  • To evaluate the performance of BEPSO and AHPSO against established PSO variants and other state-of-the-art optimization algorithms on benchmark and real-world problems.

Main Methods:

  • BEPSO incorporates eavesdropping behavior and a cognitive bias mechanism for cooperative decision-making.
  • AHPSO models particles as energy-driven agents with altruistic behavior, enabling lending-borrowing relationships.
  • Both algorithms were tested on high-dimensional CEC'13, CEC'14, and CEC'17 test suites and constrained real-world optimization problems.

Main Results:

  • BEPSO and AHPSO demonstrated statistically significant improvements over multiple comparator algorithms on unconstrained and constrained optimization tasks.
  • On the CEC13 test suite, BEPSO and AHPSO outperformed 10 out of 15 algorithms.
  • On the CEC17 test suite (50D and 100D), BEPSO and AHPSO outperformed 11 out of 15 algorithms.
  • BEPSO achieved the best mean rank on the constrained problem set, with AHPSO ranking third.

Conclusions:

  • The novel bio-inspired mechanisms in BEPSO and AHPSO effectively enhance swarm diversity and prevent premature convergence.
  • BEPSO and AHPSO offer competitive and often superior performance compared to existing state-of-the-art optimization algorithms.
  • These algorithms represent a promising advancement in bio-inspired optimization for both theoretical and practical applications.
