Data Visualization Contest: CREATIVITY

load contest_data

Description

The idea of the CREATIVITY visualization is to find most creative participants of the contests. They are two versions of election of the most creative authors. In the first case the most creative author write the biggest number of original lines during contest. In the second case the most creative author write the biggest number of original lines in the winner entrance.

Lines statistics

Looking for in which entry lines appear the first time

linestart = zeros(size(allLineList));
for k=1:size(d,2),
    entry = d(k).lines;
    for l=1:size(entry,1),
        if linestart(entry(l))==0,
            linestart(1,entry(l)) = k;
        end
    end
end

% Pass over two most popular lines
% line 3 - 'end'
% line 4 - 'function moves = solver(board)'
linestart(3:4)=0;

The biggest number of original lines during contest

Looking for authors of original lines

uls = unique(linestart);
uls = uls(2:end);
autor = cell(size(uls));
autors = zeros(size(uls));
for k=1:size(uls,2),
    autor{1,k} = d(uls(k)).author;
    autors(1,k) = sum(uls(k)==linestart);
end;

% Looking for the most original authors (number of original lines)
ua = unique(autor);
hmc = zeros(size(ua));
for k=1:size(ua,2),
    hmc(1,k) = sum((strcmp(ua(k),autor)).*autors);
end
[hmc, nr] = sort(hmc,'descend');

% N authors with the bigest number of original lines
N = 20;
aut = cell(1,N);
for k=1:N,
   aut(1,k) = ua(nr(k));
end

% Figure
barh(1:N,hmc(1:N))
axis([1 max(hmc(1:N)) 0 N+1])
set(gca,'YTick',1:20)
set(gca,'YTickLabel',aut)

The biggest number of original lines in the winner entrance

The best solution

bentry = zeros(size(d));
for k=1:size(d,2),
    bentry(k) = d(k).score;
end
bestentry = find(bentry==min(bentry));

% Lines in the best solution
linestartbest = linestart(d(bestentry).lines);

% Looking for authors of original lines
ulsb = unique(linestartbest);
ulsb = ulsb(2:end);
autorb = cell(size(ulsb));
autorsb = zeros(size(ulsb));
for k=1:size(ulsb,2),
    autorb{1,k} = d(ulsb(k)).author;
    autorsb(1,k) = sum(ulsb(k)==linestartbest);
end;

% Looking for the most original authors (number of original lines)
uab = unique(autorb);
hmcb = zeros(size(uab));
for k=1:size(uab,2),
    hmcb(1,k) = sum((strcmp(uab(k),autorb)).*autorsb);
end
[hmcb, nrb] = sort(hmcb,'descend');

% N authors with the bigest number of original lines
N = 20;
autb = cell(1,N);
for k=1:N,
   autb(1,k) = uab(nrb(k));
end
