This paper analyzes a dynamic voting model where individual preferences evolve through experimentation. Individual votes reflect not only current preferences but also the anticipated effect of elected alternatives on future preferences and votes. The analysis is conducted in a two-arm bandit model, with a safe (status quo) alternative and a risky(More)
High-frequency realized variance approaches offer great promise for estimating asset prices' covariation, but encounter difficulties connected to the Epps effect. This paper models the Epps effect in a stochastic volatility setting. It adds dependent noise to a factor representation of prices. The noise both offsets covariation and describes plausible lags(More)
The recovery of muscle weight and contraction tension was measured in rat anterior tibialis muscle following unilateral crushing of the lateral popliteal nerve. Muscle twitch and tetanic tensions and muscle weight had recovered to control values within 6-8 weeks after the nerve was crushed. Capillary supply to each of the four types of muscle fibre present(More)

Evolutionary multi-objective algorithms are widely considered to have two goals: convergence towards the true pareto front and maintaining a diverse set of solutions. Here we are primarily concerned with the first goal of convergence, in particular when one or more variables must converge to a common value. Using a well-known test suite, we discuss the(More)
