The Genetic Algorithm (GA) and Simulated Annealing (SA), two techniques for global optimization, were applied to a reduced (simplified) form of the phase problem (RPP) in computational crystallography. Results were compared with those of ''enhanced pair flipping'' (EPF), a more elaborate problem-specific algorithm incorporating local and global searches. Not surprisingly, EPF did better than the GA or SA approaches, but the existence of GA and SA techniques more advanced than those used in this study suggest that these techniques still hold promise for phase problem applications. The RPP is, furthermore, an excellent test problem for such global optimization methods.

Exact isomorphisms with formal systems which employ the standard linguistic notations are established for Spencer-Brown's primary algebra and F. J. Varela's calculus for self-reference. The primary algebra is “essentially isomorphic” with classical propositional calculus, and the calculus for self-reference translates isomorphically into an axiomatization of S. C. Kleene's three-valued logic of partial recursion. This correlates Varela's “autonomy” with “total recursive undecidabilily,” and it suggests the use of Kleene-Varela type systems for discussing “mechanically unknowable” or empirically untestable system properties.

Reciprocal altruism and inclusive fitness are generally considered alternative mechanisms by which cooperative, altruistic traits may evolve. Here we demonstrate that very general versions of Hamilton's inclusive fitness rule (developed by Queller) can be applied to traditional reciprocal altruism models such as the iterated Prisoner's dilemma. In this way we show that both mechanisms rely fundamentally on the same principle - the positive assortment of helping behaviors. We discuss barriers to this unified view, including phenotype/genotype differences and non-additive fitness (or utility) functions that are typical of reciprocal altruism models. We then demonstrate how Queller's versions of Hamilton's rule remove these obstacles.

Certain general principles of regulation and control are developed and substantiated by means of evidence from a variety of fields. First, success in regulation is a function of several variables including adaptability, use of heuristic devices, system structure and characteristics of its constituent parts. Second, both internal specialization of a system and the variety of its dependencies on the environment are important. However, while the variety is important only in the short‐run, system structure is important both in the short‐run and the long‐run. Third, according to the contemporary cybernetic paradigm, a self‐regulatory system must be an open system. This is concluded to be a myth. The theory is developed and illustrated.

Neural network (NN) implementation using the general scheme of many-valued (MV) quantum computing (QC) is presented in this paper. The proposed method uses the many-valued orthonormal computational basis states to implement such computations. physical implementation of NNQC is performed by controlling the potential to yield specific wavefunction as a result of solving Shrodinger's equation that governs the dynamics of QC.

The n-player prisoner's dilemma (Pd) is a useful model of multilevel selection for altruistic traits. It highlights the non zero-sum interactions necessary for the evolution of altruism as well as the tension between individual and group-level selection. The parameters of the n-player Pd can be directly related to the Price equation as well as to a useful alternative selection decomposition. Finally, the n-player Pd emphasizes the expected equilibrium condition of mutual defection in the absence of higher levels of organization and selection.
