This paper will focus on Miller's specific methods with which he depicts Willy's inner world. To be exact, he borrowed some techniques from the films to achieve a free exchange of space and time, that is, to make Willy's remembrance and illusion audio-visual, making the play characteristic of the films.展开更多

Miller's contribution to modern drama lies in making a good expression of the common's tragedy in his drama. Thus he is called as"an American Ibsenian playwright". The Death of a Salesman, Miller's masterwork, presents a society in pursuit of"success". In it, the hero is just a poor man with failures, and his disillusionment of dream ends up with his tragic death. This thesis primarily summarizes the former studies of the Death of a Salesman, and from a novel prospective, focuses on exploring the reasons and results of the hero's loneliness, so as to further the study of the tragic spirit in it.展开更多

The focus was laid on the improvements of ant-cycle (AC) algorithm based on the analysis of the performances of simulated annealing (SA) and AC for the traveling salesman problem (TSP). The Metropolis rules in SA were applied to AC and turned out an improved AC. The computational results obtained from the case study indicated that the improved AC algorithm has advantages over the sheer SA or unmixed AC.展开更多

First, a partial closed route that only consists of three cities is given; then other cities are added to this route by a greedy procedure successively. Implemented on a personal computer, this algorithm finds optimal solutions for 24 out of 27 standard benchmarks, and outperforms the Full Subpath Ejection Algorithm (F-SEC) proposed by Rego in 1998.展开更多
