Console games are typically programmed more efficiently than PC games because the games are designed and optimized to run on one particular type of machine.
On PCs, games must be programmed to work on thousands of hardware combinations. Very often console-coded games are ported over to PCs and therefore run less efficiently. Games that run less efficiently are optimized, and do not use the minimal amount of resources.
It is important for many games to be efficient, as this would allow machines to run the game at the most optimal speed, giving the user the best experiance. True efficiency of a particular program is subject to argument, as programs certainly do become more resource-intensive throughout time as computers' power is put to the task of operating heavier data calculations.
However, processing power can also be abused and result in a program that is programmed inefficiently. Efficiency varies from program to program, but is often taken into consideration still so a program can run better on an older machine. In Scratch , optimization is important for larger projects because Scratch is an interpreted language. Compiled machine code that runs on the computer reads other codes or "interprets" them which causes Scratch to be resource-intensive.
Furthermore, in Scratch most of the rendering is done by the processor, which makes it even more CPU-intense. Efficient programming also allows you to have more content or a smaller file size in a Scratch project, because the scripts would take up less space, letting you make more use out of 50 MB. One common problem that makes projects slow is the use of multiple very similar scripts. Take the following, for example:. Another common issue that causes Scratch projects to slow down is the use of Graphic Effects.
The removal of Pixel Bender support in the flash player makes these blocks very slow. This script, for example, would cause a project to lag:. The exceptions to this are the "ghost" and "brightness" effects. While they may slow things down a little bit, it won't lag nearly as much as the other effects, because the "ghost" and "brightness" effects did not go through Pixel Bender. The use of Custom Blocks is another factor that can slow down a project immensely.
Going from Pseudocode. Going from Java. The standard way of comparing different algorithms is by comparing their complexity using Big O notation. In practice you would of course also benchmark the algorithms. As an example the sorting algorithms bubble sort and heap sort has complexity O n 2 and O n log n respective. There are several different types of economic efficiency.
The five most relevant ones are allocative, productive, dynamic, social, and X- efficiency. Allocative efficiency occurs when goods and services are distributed according to consumer preferences. The efficiency is the energy output, divided by the energy input, and expressed as a percentage. Units are Joules J. Let's compare the definition of these two important values : Efficiency means skillfulness in avoiding wasted time and effort; careful use of resources.
Effectiveness means producing an intended result; able to accomplish a purpose. They clearly have different meanings. The efficiency formula is a measure of the efficiency of processes and machines.
Efficiency signifies a peak level of performance that uses the least amount of inputs to achieve the highest amount of output. Efficiency requires reducing the number of unnecessary resources used to produce a given output including personal time and energy. In my views, efficiency is a quality and skill as well. You can take it as a skill to some extend. How to Be More Efficient Set deadlines for each of your tasks.
Break projects down into smaller tasks. Work around other people. Work within ultradian rhythms. Listen to white noise. Find an accountability partner. Silence your inner perfectionist. Everyone wants more time. Efficiency is one way of adding minutes or hours to your day.
Here are eight tips effectively used by the most efficient. Stop Multitasking. Use Appropriate Communication. Apply Structure to the Schedule. Give Everything a Proper Place. Time Activities.
Commit to Downtime.
