Playing Safe

We consider two-player games over graphs and give tight bounds on the memory size of strategies ensuring safety conditions. More specifically, we show that the minimal number of memory states of a strategy ensuring a safety condition is given by the size of the maximal antichain of left quotients with respect to language inclusion. This result holds for all safety conditions without any regular...

Going for Broke and Playing it Safe: Dynamic Competition with Choice of Variance

We consider a differential game, in which the joint choices of the two players influences the variance, but not the mean, of the one-dimensional state variable. We interpret this state variable as a summary of how far ‘ahead’ player 1 is in the game. The flow payoffs that the players enjoy are a continuous, monotonic and bounded function of this state variable. In any Markov Perfect Equilibrium...

Is it safe for Multiple Sclerosis patients to fast?

Ramadan fasting predispose multiple sclerosis (MS) patients to a great challenge. Clinicians should have practical knowledge about the effects of fasting on MS. A mini-symposium was held in 2013 to answer the common questions about fasting in MS patients. In current review we present a summary of the mentioned mini-symposium.Generally, fasting is possible for most stable MS patients. Thorough m...
