Greedy Recombination and Genetic Search on the Space of Computer Programs
TL;DR: This paper presents the Greedy Recombination operator RB(n) for genetic programming, which performs greedy selection among potential crossover sites of a mating pair and forms the class of constructional problems, which allow precise control over the fitness structure in the space of expressions being searched.

Can natural selection favour altruism between species
TL;DR: A spatial population genetic model of two interacting species is developed, showing that indiscriminate between species helping can be favoured by natural selection, and supports Darwin's suggestion that natural selection does not favour traits that provide benefits exclusively to individuals of other species.

Estimating fluctuating selection in age-structured populations
TL;DR: It is shown that the combined effect of selection on traits at different ages acts through the individual reproductive value defined as the stochastic contribution of an individual to the total reproductive value of the population the following year.

Class Structure, Demography, and Selection: Reproductive-Value Weighting in Nonequilibrium, Polymorphic Populations.
TL;DR: It is shown that reproductive values can be defined as time-dependent weights satisfying dynamical demographic equations that depend only on the average between-class transition rates over all genotypes, which yields a simple Price equation where the nonselective effects of between- class transitions are removed from the dynamics of the trait.

Origins of altruism diversity i: the diverse ecological roles of altruistic strategies and their evolutionary responses to local competition
TL;DR: The results contribute to explaining the observed natural diversity of altruistic strategies, reveal the necessary connection between the evolution and the ecology of sociality, and correct the widespread but inaccurate view that local competition uniformly impedes the evolution of altruism.
