Step 6 - If D 0 choose the point S = (x i - 1, y i + 1). We will use the hunt-and-kill algorithm to generate mazes and use the depth-first search algorithm to solve them. We describe new algorithms and tools for generating paintings, illustrations, and anima. Step 3 - Repeat up to step 8 while P ≤ Q. Step 2 - Set the decision parameter D = 3 - 2R. The general structure of a simple genetic algorithm is shown in Figure 1, in which t is the generation number, and P(t) is the population during generation t.

Step-2: Calculate the value of initial decision parameter P0 as - P0 3 2 x R > P0 3 2 x 10 > P0 -17.

Step-1: Assign the starting point coordinates (X0, Y0) as. Step 1 - Get the coordinates of the center of the circle and the radius, and store them in x, y and respectively A. Centre Coordinates of Circle (X0, Y0) (10, 10) Radius of Circle 10.

If d 0, then S (X + 1, Y-1) must be chosen as the next pixel.

This can be decided by the d decision parameter. Instead, we need to choose the closest pixel position to complete the arc.įrom the following illustration you can see that we have placed pixel at location (X, Y) and now we need to decide where to place the next pixel - in N (X + 1, Y) or in S (X + 1, Y-1). We cannot display a continuous arc on the 'raster display. The equation of the circle is $ X ^, $ where r is the radius. These algorithms are based on the idea of determining the subsequent points needed to draw the circle. There are two popular algorithms for generating a circle: Bresenham Algorithm and Median Circle Algorithm.

Together with his students from the National University of Singapore, a series of visualisations were developed and consolidated, from simple sorting algorithms to complex graph data. Drawing a circle on the screen is a bit complex than drawing a line. VisuAlgo was conceptualised in 2011 by Dr Steven Halim as a tool to help his students better understand data structures and algorithms, by allowing them to learn the basics on their own and at their own pace.
