			A '''kinetic sorted list''' is a [[kinetic data structure]] for maintaining a [[List_(computing)\|list]] of points under motion in sorted order. It is used as a kinetic [[predecessor]] data structure, and as a component in more complex kinetic data structures such as [[kinetic closest pair]].

			== Implementation ==
			This data structure maintains a list of the elements in sorted order, with the certificates enforcing the order between adjacent elements. When a certificate fails, the concerned elements are swapped. Then at most three certificates must be updated, the certificate of the swapped pair, and the two certificates involving the swapped elements and the elements of the sorted list which directly follow in precede and follow the swapped pair.

If the certificate [C<D] fails, the list will be updated to {A,B,D,C,E,F}, and the certificates [B<C], [C<D], and [D<E], will be replaced with [B<D], [D<C], and [C<E], respectively. The new set of certificates will be [A<B], [B<D], [D<C], [C<E], [E<F]

			== Analysis ==
			This kinetic data structure is:
			* '''[[Kinetic data structure#Performance\|Responsive]]:''' a certificate failure causes one swap (which takes O(1) time) and O(1) certificate changes which take O(log n) time to reschedule
			* '''[[Kinetic data structure#Performance\|Local]]:''' every element is involved in at most 2 certificates
			* '''[[Kinetic data structure#Performance\|Compact]]:''' there are exactly {{math\|<var>n</var>-1}} certificates for a list of {{math\|<var>n</var>}} elements
			* '''[[Kinetic data structure#Performance\|Efficient]]:''' this data structure causes no extraneous [[Kinetic data structure#Certificates Approach\|internal events]], every change in the ordering of the elements causes exactly one certificate failure.

			== Generalization ==
			This data structure can be generalized to a kinetic data structure which can return a sorted list of points in <math>O(n \log m)</math> time and processes <math>O(\frac{n^2}{m})</math> events total, assuming [[kinetic data structure#Types of Trajectories\|pseudo algebraic]] trajectories, where <math>m</math> is a parameter of the data structure. Thus, a maintenance-time versus query-time tradeoff can be made to tune to specific applications.

			In the generalized data structure, the points are partitioned arbitrarily into m subsets of size <math>O(\frac{n}{m})</math>, and kinetic sorted lists are maintained on the subsets. Each sorted sublist needs to process <math>O(\frac{n^2}{m^2})</math> events (certificate failures) maximum, since there are <math>O(1)</math> swaps of each of the <math>O(\frac{n^2}{m^2})</math> pairs of elements. Thus the total time required to maintain the data structure is <math>O(\frac{n^2}{m})</math>. Requests for the sorted list can then be answered in <math>O(n\log m)</math> by merging the sorted sublists with [[mergesort]].

Home improvement can be great for the do-it-yourself homeowner, or the homeowner who likes to hire a professional to take on the project. Either way, you can't go wrong with making repairs and doing some upgrading as long as you follow these tips and advice on how to avoid pitfalls and make the best decisions possible. Keep your partially used can of drywall compound from drying out between uses! All you have to do scrape and wipe the insides of the can down to the surface of the remaining drywall mud. Next, pour just enough water onto the mud to cover its surface. Before you use it again just pour off the water and it will be as good as new! Self adhesive drywall patches are a must-have home improvement. These patches come in many forms ranging from mesh drywall tape to those made of a polymer material. Press them carefully into place using an iron. Be careful not to scorch the patch or the wall surface. Paint right over the patch and you'll never know it's there. One simple home improvement project that will leave your house looking fresh and new is painting. Choose neutral colors like light blues or subtle greens. Touch up the ceilings in colors like eggshell, white or cream. Top off the look with crown molding and remember that there are kits to help you achieve a professional look even if you have very little experience. Buying used chairs with bad upholstery on the seat portion isn't all bad. A lot of times, you can easily remove the seat, take out the staples holding the stretched fabric across the cushion and switch it out. You can mix match any fabric of your choice, and staple it back to the bottom with a heavy duty stapler. The clear and accurate establishment of a budget is crucial for the success of your home improvement project.

One of the easiest and most commonly overlooked home improvements that should be undertaken when moving into a new home is to replace every single lock in the house. While many realtors handle this service, failure to change the locks is a potential invitation to disaster. This is the first thing that should be done during the moving process. If your house has no shower, you should think about installing one. Showers are more accessible than bathtubs, and they use less water. As compared to baths, a short shower utilizes under 25 percent of the water needed for a complete tub soak. To remove green algae from your vinyl siding, mix a few cups of vinegar and a big squirt of dish or laundry detergent into a bucket of hot water. Apply the mixture and scrub with a sponge mop from top to bottom and rinse well with water from a garden hose, sprayer or power washer. Most people don't think of their circuit breakers until they lose power unexpectedly. One of the best things you can do to improve the safety and efficiency of your home is to regularly test your breakers by switching them on and off at least once yearly. This clears the breaker contacts of any built-up corrosion and allows them to work more efficiently and safely. If your breakers frequently trip, this may indicate potential safety issues that require an electrician. Brighten up tired furniture with slipcovers. If your furniture is worn or stained, or you just want to change the look of your room, use slipcovers. They come in a large variety of fabrics, and are available in solid colors or patterned. A great feature of slipcovers is that they are washable, which is very handy if you have kids or pets! Whether you are improving your own personal residence or an investment property that you will use for resale or renting, the tips we have discussed in this article will set you well on your way to higher property values as well as hassle free and financially responsible remodeling projects.
