Three Taboos

Several other rules, dictated by the Mysterious Master (Xuanzi) who first received the Nine Elixirs from the Yellow Emperor, are listed in the commentary to this text under four headings the Five Interdictions [wuji), the Three Taboos (sanhui), the Four Calamities (sibai), and the Six Adversities (liuwei). The Five Interdictions concern days on which the compounding of the elixir and related actions should not take place. These are... 

Problems arise in two situations firstly, if the molecule is linear, no complete set of 3N — 6 internal coordinates is possible. For this case, a method for constructing PES in terms of Cartesian coordinates could be used.56 Secondly, if the molecule is planar, atom-atom distances (or their reciprocals) cannot provide a complete set of internal coordinates, since they cannot describe out-of-plane motion. However, we have found the coordinates Zn so useful that we retain these coordinates and avoid planar geometries (except for three atoms, when only linear geometries are taboo). That is,... 

The methods of simulated annealing (26), genetic algorithms (27), and taboo search (29) are three of the most popular stochastic optimization techniques, inspired by ideas from statistical mechanics, theory of evolutionary biology, and operations research, respectively. They are applicable to our current problem and have been used by researchers for computational library design. Because SA is employed in this chapter, a more-detailed description of the (generalized) SA is given below. 

Efros productions of Chekhov s The Seagull in 1966 and The Three Sisters in 1967 aroused huge controversy, since Efros interpreted the plays in terms of the lack of communication that is characteristic of the theatre of the absurd, another taboo in Soviet theatre. This led to his dismissal from the Lenkom and his transfer to the position of staff director at the Malaya Bronnaya Theatre. Here he directed classical dramas and developed both his method of structural analysis for the exploration of character psychology and his concept of psycho-physics - the psychological motivation of movement.
