Correct answer will be upvoted else Multiple Downvoted. Computer science. every subject (aside from precisely one), there exists an essential theme (for the point I, the essential point is pi). Ivan can't give a talk on a subject prior to giving a talk on its essential theme. There exists no less than one substantial requesting of themes as per these essential imperatives. Requesting the subjects effectively can assist understudies with understanding the talks better. Ivan has k uncommon sets of points (xi,yi) with the end goal that he realizes that the understudies will comprehend the yi-th subject better if the talk on it is led just after the talk on the xi-th theme. Ivan needs to fulfill the requirements on each such pair, that is, for each i∈[1,k], there should exist some j∈[1,n−1] to such an extent that qj=xi and qj+1=yi. Presently Ivan needs to know whether there exists a requesting of subjects that fulfills this multitude of imperatives, and if something like one exists,…
Consider the problem of learning the target concept "pairs of people who live in the same house," denoted by the predicate HouseMates(x, y). Below is a positive example of the concept. HouseMates (Joe, Sue) Person(Joe) Person(Sue) Sex(Joe, Male) Sex(Sue, Female) Hair Color (Joe, Black) Haircolor (Sue, Brown) Height ( Joe, Short) Height (Sue, Short) Nationality (Joe, US) Nationality (Sue, US) Mother(Joe, Mary) Mother (Sue, Mary) Age (Joe, 8) Age (Sue, 6) The following domain theory is helpful for acquiring the HouseMates concept: HouseMates(x, y) t InSameFamily(x, y) HouseMates(x, y) t FraternityBrothers (x, y) InSameFamily(x, y) t Married(x, y) InSame Family ( x y) t Youngster (x) A Youngster ( y ) A SameMother ( x, y ) و SameMother(x, y ) t Mother (x, z) A Mother (y, z ) Youngster (x) t Age(x, a ) A LessThan(a, 10) Apply the PROLOG-EBGalgorithm to the task of generalizing from the above instance, using the above domain theory.
