\uD83E\uDD14 Problem Statement
Research Optimization Legacy Code
Code Breakdown
Function: “load_course_map“
Parameters: The name of the course we’re trying to load in (course_name)
Returns: The map of elevations on said course (elev_profile).
The map of elevations has dimensions num_points x 2, with column 1 (Index 0) representing the y-coordinates and column 2 (Index 1) representing the x-coordinates.
Function: “generate_initial_profile“
Parameters: The maximum allowable time to cover a distance in seconds (time), the distance to be covered in meters (distance), the list of pitches map of elevations that the car must travel (e_profile), the minimum allowable velocity (min_velocity), and the list of indices where the car must stop (stop_profile)
Returns: A map of the same dimensions as the map of elevations with each element representing the average velocity required for the car to move at each point on the map of elevations (initial_profile).
Ex. initial_profile[2] = 10 means that according to the initial profile, the car should be moving 10 m/s at point 3 (Index 2) on the map of elevations.
This function basically generates the naive/initial solution that will be improved upon through the optimization function later in the program.
Function: “objective“
Parameters: The velocity profile (v_profile)
Returns: The amount of energy used by the car as a result of driving at the stated velocities in v_profile throughout each point on the map of elevations (energy / 100000). The energy usage is calculated by a function located in car_model.py
This objective function will be minimized by the optimization function later in the program because we’d want to minimize how much energy the car uses.
Function: “time_constraint“
Parameters: The velocity profile (v_profile)
Returns: Time spent driving as a result of moving at the stated velocities in v_profile throughout each point on the map of elevations subtracted from the maximum allowable time by the competition. (time-sum(time_used))
Basically returns how much more time we used than is allowed.
Time used by the v-profile shouldn’t be greater than the maximum time allowed by the competition.
Used as a constraint for the optimization function later in the program
Function: “speed_constraint“
Parameters: The velocity profile (v_profile)
Returns:
