Understand the Problem
The question is asking for the identification of various programming concepts related to the Knapsack problem, graphical display methods in Python, and saving plots using PyLab. It also requests explanations for specific functions in Python, namely 'show()' and 'legend()'.
Answer
1) 0/1 Problem 2) show() 3) .png 4) savefig() 5) Displays figures. 6) Adds legend.
- Knapsack problem is also known as the '0/1 problem'. 2) The 'show()' method displays the graphical window on the computer screen. 3) When storing a PyLab Figure, the default extension is '.png'. 4) The 'savefig()' function is used to save a plot graph to a file. 5) The 'show()' function in Python is used to display figures and pause the script until the plot window is closed. 6) The 'legend()' function in Python adds a legend to the plot, which is useful for identifying different plotted data series.
Answer for screen readers
- Knapsack problem is also known as the '0/1 problem'. 2) The 'show()' method displays the graphical window on the computer screen. 3) When storing a PyLab Figure, the default extension is '.png'. 4) The 'savefig()' function is used to save a plot graph to a file. 5) The 'show()' function in Python is used to display figures and pause the script until the plot window is closed. 6) The 'legend()' function in Python adds a legend to the plot, which is useful for identifying different plotted data series.
More Information
The 'show()' function is crucial for interactive plotting as it displays figures in a window, while the 'savefig()' function preserves figures to files. Legends enhance readability by labeling plot elements.
Tips
For the 'show()' function, ensure the environment supports graphical display. For 'savefig()', remember to specify the file format if needed.
