They are artificially intelligent. They watch thousands of hours of videos of the game they are going to play. After they learn, they challenge themselves against themselves and save all the moves it used that time, they play another game against the saved game and if they best it then they save the new and repeat. I am not sure about this because I am just a 15 yr old but the early ones brute forced the game and one. Brute Forcing is a way to try out every possible move and pick the most like to succeed or the most efficient one, brute force is also used in hacking or cracking passwords that have something in common. Like let's say ur password is Jakeis35. I would make a list that would be:
Jake
jake
Is
is
35
34

and with a software it will put together every possible pair and will stop when it matches the password on the server or if the password let it login.

What are entity-relationship diagrams and how are they used? What symbol is used for a relationship? What is an associative enti
castortr0y [4]

Answer:

The definition including its given problem is outlined in the following segment on the clarification.

Explanation:

  • Entity-relationship (ER) diagram describes how mechanical stored procedures are constructed and demonstrate the overarching representation of the situation. It also describes the connections between some of the entities of the framework and even the comparison with standard measurements.
  • For something like an individual relationship structure, the normal representation of connections seems to be a diamond. Associative institutions have several to many partnerships to communicate with. It's indeed the verb throughout a diamond-shaped form that holds two organizations around each other. This verb is in fact an entity on its own, therefore it must be termed an associative entity.
  • An illustration of such might be if a participant were to register for a class. Multiple individuals will be registered for several courses, and there have been many to several relationships; thus, the associative object will indeed register.

This program is to compute and write to a file the GPA for student scores read from an input file. The point values of the grade
VARVARA [1.3K]

Answer:

#Take input from the user

filename=input('Enter name of input file: ')

total_units=0#Total number of units for a student

total_score=0#Total score of a student

#Assign a score to each grade. I have reduced 0.33 for each grade. Change here if you need to

grade={'A':4.0,'A-':3.67,'B+':3.34,'B':3.01,'B-':2.68,'C+':2.35,'C':2.02,'C-':1.69,'D+':1.36,'D':1.03}

try:

with open(filename,"r") as input_file:#Open the file for input(reading)

output_file=open("GPA_output.txt","w") #Create and open GPA_output.txt if it doesn't exist for writing

for student_record in input_file:#read from input file

if("," in student_record):#if there is a , that means this is the student name

student_name=student_record.strip('\n')#Remove \n from student name

continue

else:

if(" " in student_record):#If a line contains spaces then its the student's grades for a course

student=student_record.split(" ")#Split to find the coursename, units and grade

#student[0]=coursename student[1]=units student[2]=grade

total_units+=int(student[1])#Calculate total units for 1 student

total_score+=int(student[1])*grade[student[2].strip('\n')]#Find the total score of a student

#grade[student[2]] will lookup for the score that we initialized earlier

#if student has a grade as A then this will look up as grade['A'] which will return 4

#Find the total score as product of this grade and units for this course

continue

else:

if(total_units>0):#Check if score has been calculated for a student earlier

print("in")

GPA=total_score/total_units#Calculate the GPA

output_file.write("%-26s%.2f\n" % (student_name, GPA))#Write the GPA and Student Name in the required format

total_units=0#reset the units

total_score=0#reset the score

if(total_units>0):#Essential for the case when the file doesn't end with a new line(Check if total_units is not 0) which means a record is pending

#to be written to the file

GPA=total_score/total_units#Calculate the GPA

output_file.write("%-26s%.2f\n" % (student_name, GPA))#Write the GPA and Student Name in the required format

total_units=0#reset the units

total_score=0#reset the score

input_file.close()#Close the input file

output_file.close()#Close the output file

except IOError as e:

print("Problem in Opening the required file")#Print a message if file cannot be opened

Explanation:

The program has been tested for all 3 scenarios mentioned i.e.

a. If the file ends without \n

b. If the file ends with 2 \n

c. If the file ends with 1 \n

PS: The Program will run irrespective of how it ends. Even if there are many \n at the end of file, the program will be fine.
