This program simulates fantasy basketball games based on a provided database of players and reports various statistical results.
The player database takes the form of a configuration file passed to the program via a command-line argument. The configuration file must possess a specific format; an example is provided below.
player_database = [
{
name = "Joel Embiid";
positions = ["PG","SG","PF","SF","C"];
rank = 1;
draft_range_begin = 1;
draft_range_end = 6;
points = 34.70;
rebounds = 11.00;
assists = 5.60;
steals = 1.20;
blocks = 1.70;
threes = 1.40;
field_goals_made = 11.50;
field_goals_attempted = 21.80;
free_throws_made = 10.20;
free_throws_attempted = 11.60;
},
{
name = "Nikola Jokic";
positions = ["PG","SG","PF","SF","C"];
rank = 2;
draft_range_begin = 1;
draft_range_end = 6;
points = 26.40;
rebounds = 12.40;
assists = 9.00;
steals = 1.40;
blocks = 0.90;
threes = 1.10;
field_goals_made = 10.40;
field_goals_attempted = 17.90;
free_throws_made = 4.50;
free_throws_attempted = 5.50;
},
{
name = "Shai Gilgeous-Alexander";
positions = ["PG","SG","PF","SF","C"];
rank = 3;
draft_range_begin = 1;
draft_range_end = 6;

For optimization reasons, certain settings must be configured in the program before compilation. These settings can be found in include/user_settings.hpp.

The simulation involves randomly generating leagues, scoring the teams, and then recording the results. Although I said 'random', the generation is biased in such a way to better reflect reality. For example, it will take into acccount properly filling the various positions on a team and the likelihood that a player will be drafted in a specific round.
During the simulation, the program will print the percent completed and the estimated time remaining. When the simulation is finished, the program will print the total time taken. All of this is printed to stderr so as not to interfere with the printing of the main results.
After running the simulation, the program will print two sets of statistics in CSV format to standard output.
Note that the "player statistics categories" as mentioned below are: points, rebounds, assists, steals, blocks, 3's, field goals, free throws.
The first consists of the probabilities that each player will be drafted in a team whose rank is 1 or 1-4 (Mr. Brown tells me that the number 4 is important for some reason...) in each of the player statistics categories.
The second consists of mean, minimum, maximum, and standard standard deviation of each of the player statistics categories for each team ranked 1-... in each of the player statistics categories.
