什么是算法？

Question

class Athlete:
  def __init__(self, name, points):
    self.name = name
    self.points = points

  def calculateRacePoints(name):
    for i in range(eventTotalVar):
      racePoints = checkOverallPlacement(placementVar, eventType=eventVar) + checkPercentagePlacement(placementVar, totalVar, eventType=eventVar) + checkImprovement(seedTime, prelimTime, finalTime) # uses created 2 functions and finds the total
      racePoints = racePoints + racePoints

    return float(racePoints / eventTotalVar)

This is basically creating an athlete with inputted specifications. It will return the average points attained in the race (total points divided by number of events).

Do classes qualify as an algorithm? If so, do my two functions within it also qualify as an algorithm? What specifically makes an algorithm, well, an algorithm?

Answer 1

Oxford Dictionary defines an Algorithm as:

"A process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer".

By that definition something as simple as print("Hello World") would technically be considered an algorithm.

looking at your code:

class Athlete:
  def __init__(self, name, points):
    self.name = name
    self.points = points

  def calculateRacePoints(name):
    for i in range(eventTotalVar):
      racePoints = checkOverallPlacement(placementVar, eventType=eventVar) + checkPercentagePlacement(placementVar, totalVar, eventType=eventVar) + checkImprovement(seedTime, prelimTime, finalTime) # uses created 2 functions and finds the total
      racePoints = racePoints + racePoints

    return float(racePoints / eventTotalVar)

You have multiple algorithms at work.

class Athlete

• Contains two or more algorithms
• Contains logical and mathematical concepts

def __init__(self, name, points)

• Solves the problem of describing who or what the athlete is
• It allows you to create an athlete and give that athlete a name and score/points

def calculateRacePoints(name)

• Solves the problem of interacting with the athlete
• It allows you to get information about this athlete's score/points

Both of your class methods are algorithms that work together to help the program create new athletes and interact with them.

I would imagine you need to provide more detail to complete the assignment, but I hope this gets you started.
