  3. "Take it or leave it." • A friend is looking for a mate • Goal: Find matches that meet criterion number of desirable attributes in a mate: • honesty, intelligence, beauty, lets you cheat off them… • Different people have different numbers of these attributes - we give them a “score” based on the number of desirable attributes they have. - we can describe the population by a distribution on this score. • Picky friend makes a wants a “12”. • How hard will that be to achieve?

  4. Prospect distribution • Prospect’s scores are normally distributed and have mean 6, standard deviation 3. • Scores can be negative, but all scores are integers. Meanscore = 6; Stdscores = 3; NumberProspects = 1000; prospects=ceil(6+3*randn(1,NumberProspects)) This is your dating pool

  5. How many prospects for friend? goodones=find(prospects >= 12)

  6. Now what? • Which dates should the friend take? • How many possible matches? • That depends on the PROSPECT’s criteria • We need to know our friend’s score. Say it is a “10” • Assign each PROSPECT a criteria. • Let us say PROSPECT criteria are about +/-2 points from their own score on average. • Finally MATCHES are made first date that both exceed criteria.

  7. PROSPECT CRITERIA prospectcriteria=ceil(prospects+2*randn(1,NumberProspects))

  8. MATCH GAME Isdatablecount =0; For possibledates=1:NumberProspects, isdatable = prospects(possibledates)>=friendscriterion isdatablecount = isdatablecount +1; if isdatable, ismatch= friendsscore >= prospectscriterion(possibledates; if ismatch, matchscore = prospects(possibledates); break; end end end

  9. Be systematic! • What is the average match scores • As a function of friend’s score? • What is the effect of • Dating pool size • Pool quality
