https://doi.org/10.1007/978-3-658-18903-7Most modeling languages embody a particular idiom: the state/invariant/operations idiom for VDM and Z; the variable-update/temporal-logic idiom for SMV and Murphi; the imperative-programming idiom for Promela and Zing; and so on. Fixing an idiom makes tools easier to build, and helps novice modellers. But it also makes the language less flexible.

Microregionalism and World OrderWe study . circle packings and circle-contact representations for planar graphs, where the ratio of the largest circle’s diameter to the smallest circle’s diameter is polynomial in the number of circles. We provide a number of positive and negative results for the existence of such balanced configurations.
