Набор точек выглядит следующим образом: < /p>

Прямо сейчас я использую этот алгоритм: < /p>
def dominates(row, candidateRow):
return sum([row[x] >= candidateRow[x] for x in range(len(row))]) == len(row)
def simple_cull(inputPoints, dominates):
paretoPoints = set()
candidateRowNr = 0
dominatedPoints = set()
while True:
candidateRow = inputPoints[candidateRowNr]
inputPoints.remove(candidateRow)
rowNr = 0
nonDominated = True
while len(inputPoints) != 0 and rowNr < len(inputPoints):
row = inputPoints[rowNr]
if dominates(candidateRow, row):
# If it is worse on all features remove the row from the array
inputPoints.remove(row)
dominatedPoints.add(tuple(row))
elif dominates(row, candidateRow):
nonDominated = False
dominatedPoints.add(tuple(candidateRow))
rowNr += 1
else:
rowNr += 1
if nonDominated:
# add the non-dominated point to the Pareto frontier
paretoPoints.add(tuple(candidateRow))
if len(inputPoints) == 0:
break
return paretoPoints, dominatedPoints
