We present a generalization of the scalar importance function employed by Metropolis Light Transport (MLT) and related Markov chain rendering algorithms. Although MLT is known for its user-designable mutation rules, we demonstrate that its scalar contribution function is similarly programmable in an unbiased manner. Normally, MLT samples light paths with a tendency proportional to their brightn...

We propose a probabilistic interpretation of a class of reversible communicating processes. The rate of forward and backward computing steps, instead of being given explicitly, is derived from a set of formal energy parameters. This is similar to the Metropolis-Hastings algorithm. We find a lower bound on energy costs which guarantees that a process converges to a probabilistic equilibrium stat...

Sydney, like all cities, is imagined in particular ways which derive from a specific sociocultural and historical context and which persist over time, even when social and economic changes render the dominant imaginary outmoded. How a city is imagined has distinct effects on how that city is planned and lived, and in this sense a mismatch between the dominant imaginary and the material reality ...

The square-root principle is known to achieve low search time for peer-to-peer search techniques that do not utilize query routing indices (e.g., query flooding or random walk searches). Under this principle, each object is probed with probability proportional to the square root of its query popularity. Existing search methods realize the square-root principle by using either object replication...

The presented article contains a 2D mesh generation routine optimized with the Metropolis algorithm. The procedure enables to produce meshes with a prescribed size h of elements. These finite element meshes can serve as standard discrete patterns for the Finite Element Method (FEM). Appropriate meshes together with the FEM approach constitute an effective tool to deal with differential problems...

Aquiet revolution has been going on in town planning and architectural circles over the last decade. Established zoning and urban design ideas are being questioned and reversed. Urban planners and designers are reviving and reinterpreting ideas that prevailed before the automobile spread our cities apart and hollowed out their cores, before mass transit became the transportation mode for an und...

“The Virtual Metropolis” is an interactive installation combining traditional ink drawings and stop motion animation with video game technology. The artwork features various intermingled imaginary environments including cityscapes, factory districts and war zones. The user is invited to explore these worlds, seamlessly moving from one area to next, to discover satirically iconic animations and ...
