Survival Probabilities of History-Dependent Random Walks
Uri Keshet, Shahar Hod
We analyze the dynamics of random walks with long-term memory (binary chains with long-range correlations) in the presence of an absorbing boundary. An analytically solvable model…
Survival probabilities in time-dependent random walks
Ehud Nakar, Shahar Hod
We analyze the dynamics of random walks in which the jumping probabilities are periodic {\it time-dependent} functions. In particular, we determine the survival probability of bias…
Evolutionary Minority Game: The Roles of Response Time and Mutation Threshold
Shahar Hod, Ehud Nakar
In the evolutionary minority game, agents are allowed to evolve their strategies (``mutate'') based on past experience. We explore the dependence of the system's global behavior on…
Phase-Transition in Binary Sequences with Long-Range Correlations
Shahar Hod, Uri Keshet
Motivated by novel results in the theory of correlated sequences, we analyze the dynamics of random walks with long-term memory (binary chains with long-range correlations). In our…
Strategy updating rules and strategy distributions in dynamical multiagent systems
Shahar Hod, Ehud Nakar
In the evolutionary version of the minority game, agents update their strategies (gene-value ) in order to improve their performance. Motivated by recent intriguing results obta…
