In the 1990s, Agent-Based Modeling (ABM) began gaining popularity and represents a departure from the more classical simulation approaches. This departure, its recent development and its increasing application by non-traditional simulation disciplines indicates the need to continuously assess the current state of ABM and identify opportunities for(More)
We briefly describe genetic algorithms (GAs) and focus attention on initial population generation methods for two-dimensional knapsack problems. Based on work describing the probability a random solution vector is feasible for 0-1 knapsack problems, we propose a simple heuristic for randomly generating good initial populations for genetic algorithm(More)
We show how to find mixing probabilities, or weights, for composite probability mass functions (pmfs) for k-variate discrete random variables with specified marginal pmfs and a specified, feasible population correlation structure. We characterize a joint pmf that is a composition, or mixture, of 2k-1 extreme-correlation joint pmfs and the joint pmf under(More)
Combat, unlike many real-world processes, tends to be singular in nature. That is, there are not multiple occurrences from which to hypothesize a probability distribution model of the real-world system. Mission-level models may offer more flexibility on some measures due to their extended time frame. Additionally, the parameters involved in the(More)
In order to assay the extent of ongoing synaptic remodelling in adult mouse neuromuscular junctions, dynamic structural changes of identified neuromuscular junctions were monitored in vivo over periods up to three months. Nerve terminal outgrowths as small as 1 micron were detectable with a new fluorescent tetanus toxin C-fragment stain combined with(More)
To date, most search theory study has focused either on analytical models of specific situations requiring rigid assumptions, or, as in the case of search and rescue, operational experiments aimed at obtaining detection probabilities for a variety of scenarios. Analytical search theory results provide bounds on empirical results. This research introduces an(More)
