Evidence for both, acceleration and deceleration of evolution through learning can be found in the literature. We suggest a selection gradient model that allows to predict whether acceleration or deceleration is predominant. The main idea is that learning alters the genotype-to-fitness landscape, which determines selection pressure. Assuming that fitness can be split up into an innate and a lea...

This position paper argues that the Baldwin effect is widely misunderstood by the evolutionary computation community. The misunderstandings appear to fall into two general categories. Firstly, it is commonly believed that the Baldwin effect is concerned with the synergy that results when there is an evolving population of learning individuals. This is only half of the story. The full story is m...

G. G. Simpson was the first to explain the Baldwin Effect completely in terms of the theory of natural selection. A genetic version of a seemingly non-hereditary adaptation may arise when natural selection acts on the likelihood of having an adaptive trait not just on the trait itself. We present a quantitative model of the Simpson-Baldwin Effect. Organisms in the model have mutable ranges of p...

Stanley Baldwin, the Conservative Party leader from 1923 to 1937, has been credited with first use of term “one nation” as a tenet politics. But it is unlikely that he intended invent new phrase, and was not source for modern conception “One Nation Conservatism”. Nevertheless, during severe difficulties inter-war Britain fears Party’s future, Baldwin did create distinctive politics which emphas...

Since Hinton & Nowlan published their seminal paper (Hinton & Nowlan 1987), the neglected evolutionary process of the Baldwin effect has been widely acknowledged. Especially in the field of language evolution, the Baldwin effect (Baldwin 1896d, Simpson 1953) has been expected to salvage the long-lasting deadlocked situation of modern linguistics: i.e., it may shed light on the relationship betw...

The Baldwin effect is known as one of the interactions between evolution and learning. In this paper we consider the Baldwin effect in dynamic environments, especially when there is no explicit optimal solution through generations and it depends only on the interaction among agents. We adopted the iterated Prisoner’s Dilemma as a dynamic environment, introduced phenotypic plasticity into strate...
