There are many multi-objective planning problems in emergency decision-making domain. HTN planners were widely used in emergency decision-making, while they have limited ability to solve optimization, especially multi-objective optimization. Aimed to handling multi-objective in HTN planners, this paper proposes a novel method based on SHOP2, which is a domain-independent state-based forward HTN planner...
OEP (Original Entry Point) search is the first and foremost step in unpacking. At present, it lacks generic and automated OEP search method for numerous types of packers. This paper discusses general methods of OEP search and proposes an OEP search method based on API-monitoring. Then the paper presents a generic OEP search strategy based on the combination of existing methods. Empirical test shows...
In order to avoid slow-convergence and local convergence of simple genetic algorithm (SGA) for intelligent test paper generation, a kind of improved genetic algorithm (IGA)has been proposed in this paper. This algorithm uses unceasing elimination of similar individual method to quickly enlarge the search space and to stabilize the individual diversity of the group. Experiment results show that the...
Through investigating and analyzing the outlet position and wastewater quality of the enterprises along the Yibin section of Yangtse River, the Yibin section of Yangtse River is divided into 5 cells based on the theory of optimal search according to the characteristic of the standardization management of the outlet. Thus the target distribution function and the search probability function are deduced,...
According to rules of ants looking for food and immune genetic thought, an ant colony genetic algorithm is proposed based on immune mechanism. In precondition of keeping characteristics of the ant colony algorithm for global optimization and getting rationality of solutions in finite time, by introducing immune mechanism, the diversity of individuals can be assured and the phenomenon of long searching...
According to the accidental pollution source that discharges discontinuously and dynamically, based on the analysis of the characteristic of the location of the outlets for discharging sewage, the legitimacy of the outlets and the pollution characteristic in a drainage area, the search area is classified into four types, and the corresponding original distribution function is suggested, thus the detection...
When the pollution accidents take place in the river basin, it is very important and necessary to find out the accidental sources of pollution , so that effective measures can be taken to reduce the pollution. But because of the lack of monitoring efforts and the secluded source, very little about the accidental sources of pollution is known to searcher and it is very hard to find the accidental sources...
The distribution method of the monitoring effort is studied by using the optimal search theory to detect the water pollution accident source for a suddenlyoccurred pollution event in the river basin. For the sudden accident by characteristic contaminants in medium-sized river, the research sets the target distribution and the detection function, and builds the optimal search model of detecting the...
