DRGS is the most widely used calculation of the optimal path in-car systems, which in the process of finding the optimal path, is very convenient. However, due to the limitation of the genetic algorithm, efficiency of the optimal path in the output there are some defects. Based on the improved genetic algorithms, serial number coding model based on turning innovative ways of encoding, in the use of in the process of solving optimal path, analyses and feasibility studies, aims at creating a new genetic algorithm for optimal path planning, and demonstrate its usefulness in terms of convergence. © 2015 IEEE.

Polyhydroximic acid (PHA) with the function of heavy metal flocculant was made by compounding polyacrylamide, hydroxylamine hydrochloride and sodium hydroxide, to observe its effects on the cadmium wastewater disposal under different conditions (pH value, different organic complexing agents EDTA, triammonium citrate, glycocoll, humic acids and turbidity). The present study reaches the following results: (1) PHA has good effects on the removal of Cd2+ in wastewater; for the sample wastewater with a concentration of 25 mg·L-1, the removal rate of Cd2+ can reach 94%; (2) The removal rate of Cd2+ rises with the rise of pH values(4-8); (3) EDTA can obviously inhibit PHA's removal rate of Cd2+; (4) Triammonium citrate can improve PHA's removing ability of Cd2+. (5) Glycocoll and humic acids can obviously enhance the removing of Cd2+; (6) Turbidity-causing materials can promote the removal of Cd2+ and turbidity. © (2012) Trans Tech Publications, Switzerland.

The problem of vehicle routing optimization is researched, to improve the efficiency of vehicle scheduling. With the increasing complexity of the traffic network, the vehicle will face the interference of accident and congestion, this situation is random and cannot be predicted. The traditional vehicle routing planning model lack of analysis of the interference risk, accurate model cannot be established, the vehicle scheduling operating efficiency is bad. In order to avoid these defects, the vehicle routing optimization method is proposed based on hybrid algorithm. According to the theory of traffic information feedback method, the feedback model of road information is established. It provides basis for vehicle routing optimization. The ant colony algorithm and extreme optimization algorithm are combined, the hybrid algorithm is obtained. According to the theory of hybrid algorithm, the vehicle routing optimization model is constructed, and related vehicle data is input in the model. The vehicle routing optimization processing is realized. The experiment results show that this algorithm can improve the scheduling efficiency, so as to meet the actual demand of traffic management. © 2014 IEEE.

In coal analysis, there exists high dimensional feature information in the dataset. However, there are several irrelative or redundant features. Feature selection algorithm could select the relative attributes, but it is possible that some important features are deleted. In this paper, we propose hierarchical clustering based logistic regression algorithm. It firstly selects multiple groups of features using random selection, and builds multiple models. After model built, it clusters the models and makes the similar models into one clustering. Finally, we use the logistic regression clustering to complete the forecast work for future dataset. © 2016 IEEE.
