Resumen
Este estudio presenta un algoritmo evolutivo multiobjetivo robusto asistido por sustituto (RMOEA-SA) para reducir los costos computacionales. El RMOEA-SA equilibra eficazmente la robustez y la optimalidad de la solución, superando a los métodos existentes.
Área de la Ciencia:
- Inteligencia computacional
- Algoritmos de optimización
- Computación evolutiva
Sus antecedentes:
- Los algoritmos evolutivos multiobjetivo robustos (RMOEA) tradicionales exigen un muestreo extensivo, lo que genera altos costos computacionales en escenarios del mundo real.
- La necesidad de métodos eficientes para lograr soluciones óptimas robustas en aplicaciones computacionalmente intensivas es crítica.
Objetivo del estudio:
- Desarrollar un algoritmo evolutivo multiobjetivo robusto asistido por sustituto (RMOEA-SA) que reduzca significativamente las evaluaciones de funciones.
- Introducir una novedosa métrica de distancia robusta (RDM) integrada con un modelo sustituto para una medición mejorada de la robustez.
- Mejorar el compromiso entre la robustez y la optimalidad de la solución aumentando el espacio objetivo.
Principales métodos:
- Implementación de un modelo sustituto de función de base radial (RBF) para aproximar los valores de aptitud, reduciendo el número de evaluaciones de funciones directas.
- Desarrollo de una métrica de distancia robusta (RDM) que utiliza el modelo sustituto RBF para cuantificar la robustez de la solución.
- Aumento del espacio objetivo incorporando el valor RDM como un objetivo adicional para la selección.
Principales resultados:
- El modelo sustituto RBF aproxima eficazmente los valores de aptitud, disminuyendo sustancialmente la carga computacional durante la optimización robusta.
- La RDM, asistida por el sustituto RBF, mide con precisión la robustez de la solución.

What is Evolutionary History?
43.6K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

Distance Problem
74
When an object's velocity changes over time, the total distance traveled can be determined by summing small displacement intervals over short increments. This approach approximates the true distance through numerical summation and the use of integral calculus. An estimate of the total displacement can be obtained by measuring velocity at regular intervals and multiplying each value by the corresponding time step.If a runner accelerates over the first three seconds of a race, speed measurements...

Evolutionary Psychology
1.0K
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...

The Distance Formula
652
In geometry, measuring the direct distance between two points on a plane is essential in various practical and theoretical applications. Whether in navigation, engineering, or computer graphics, determining the shortest path between two locations involves using the distance formula. This formula is derived from the Pythagorean Theorem, which relates the lengths of the sides of a right triangle. On a coordinate plane, the horizontal and vertical distances between two points serve as the legs of...

Distance Corrections
297
To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

Criticisms of the Evolutionary Perspective
376
In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
