tabu
Tabu search is a metaheuristic search method employing local search methods used for mathematical optimization.
It was created by Fred W. Glover in 1986 and formalized in 1989.Local (neighborhood) searches take a potential solution to a problem and check its immediate neighbors (that is, solutions that are similar except for very few minor details) in the hope of finding an improved solution. Local search methods have a tendency to become stuck in suboptimal regions or on plateaus where many solutions are equally fit.
Tabu search enhances the performance of local search by relaxing its basic rule. First, at each step worsening moves can be accepted if no improving move is available (like when the search is stuck at a strict local minimum). In addition, prohibitions (henceforth the term tabu) are introduced to discourage the search from coming back to previously-visited solutions.
The implementation of tabu search uses memory structures that describe the visited solutions or user-provided sets of rules. If a potential solution has been previously visited within a certain short-term period or if it has violated a rule, it is marked as "tabu" (forbidden) so that the algorithm does not consider that possibility repeatedly.

Hayati Magufuli aliharibu sana hii nchi, Rais Samia atapata tabu kuongoza asipokuwa mkali
Wakuu Habari Baada ya ziara ya Samia ya kwenda Kenya na kuondoa mtanziko wa kibiashara na kidiplomasia kati ya nchi hizi mbili na malori ya Tanzania kuruhusiwa kupeleka bidhaa zetu huko nilisoma maoni ya baadhi ya Watanzania ndipo nikajua Magufuli aliharibu hii nchi kiasi gani. Kwanza kitendo...- Johnny Sack

Ndugu zangu kwa mtiririko,umakini na hata namna vikao vyao huwa kwakweli napata tabu mno kuifananisha CCM na vitu vya ajabu!
CCM bado ni chama imara ki-muundo na ki-mfumo pia. Ukiangalia mpangalio wa vikao wa CCM hakika unajawa na haja ya kuwafuatilia na kuziheshimu sera na itifaki zao. Pamoja na kulalamikiwa imekuwa ikitumia dola kubaki madarakani lakini bado chama hicho kinazo sifa na uwezo wa kuendelea kuongoza...- jitombashisho

Mtoto wangu wa kike atapata tabu sana
Yaan Heb ngoja kwanza. Niseme kwamba mimi bado nakula ujana.. sina hata mtoto wa kusingiziwa.. natarajia nifanye maamuzi ya kuwa na mtoto kuanzia mwakani labda... Haijalishi wa kiume au wa kike. Ila sasa, kwa niliyoyashuhudia leo wakati wa mchana nilitoka mara moja nikaelekea mahala fulani...- Napoleone
