Life's forms

Lifes preservative against self-killing

in the "index of botanical names", where the medieval Latin designations take you to the main dictionary, for example to the items satirion and testiculus leporis, under which the Middle English names are listed, in the case of satirion indiscriminately with other possible identifications, such as Arum and Endymion. Admittedly, the difficulties of identification are considerable-one reason bein...

Hierarchies of Biocomplexity: modeling lifes energetic complexity

In this paper, a model for understanding the effects of selection using systems-level computational approaches is introduced. A number of concepts and principles essential for understanding the motivation for constructing the model will be introduced first. This will be followed by a description of parameters, measurements, and graphical representations used in the model. Four possible outcomes...

Finding Still Lifes with Memetic/Exact Hybrid Algorithms

The maximum density still life problem (MDSLP) is a hard constraint optimization problem based on Conway’s game of life. It is a prime example of weighted constrained optimization problem that has been recently tackled in the constraint-programming community. Bucket elimination (BE) is a complete technique commonly used to solve this kind of constraint satisfaction problem. When the memory requ...

Applications of quadratic D-forms to generalized quadratic forms

In this paper, we study generalized quadratic forms over a division algebra with involution of the first kind in characteristic two. For this, we associate to every generalized quadratic from a quadratic form on its underlying vector space. It is shown that this form determines the isotropy behavior and the isometry class of generalized quadratic forms.
