....the 25 joins shows the tendency that proposed optimization techniques will become intractable for super complex queries. The use of such queries is very limited and they are unlikely to become more popular in the future. Some research exists in the field of this super complex query optimization [55, 56, 39]. Stillger et al. 38] seems to present the most promising technique based on 28 genetic programming, which could be viewed as a kind of prolongation of randomized techniques (see section 3.4) Finally, it is quite interesting to look at the total memory requirement of the PTPO technique : on ....
