Also, these are intended to have a better understanding that the system is dependent and restricted to its agents and how they work cooperatively. This algorithm is designed to complete in a shorter amount of time. They are important because artificial intelligence or AI algorithms can take a long time to complete results. They are also supposed to be flexible in time and resources. The goal of anytime algorithms are to give intelligent systems the ability to make results of better quality in return for turn-around time. They are different from contract algorithms, which must declare a time in advance in an anytime algorithm, a process can just announce that it is terminating. The answer generated by anytime algorithms is an approximation of the correct answer.Īn anytime algorithm may be also called an "interruptible algorithm". Anytime algorithms, however, are able to return a partial answer, whose quality depends on the amount of computation they were able to perform. Most algorithms either run to completion or they provide no useful solution information. The amount of computation required may be substantial, for example, and computational resources might need to be reallocated.
In some cases, however, the user may wish to terminate the algorithm prior to completion. Most algorithms run to completion: they provide a single answer after performing some fixed amount of computation. The algorithm is expected to find better and better solutions the longer it keeps running. In computer science, an anytime algorithm is an algorithm that can return a valid solution to a problem even if it is interrupted before it ends. Tickets can be bought in advance or immediately before travel.īreak of journey is allowed on all Anytime Day tickets.Algorithm that can return a valid solution to a problem even if interrupted Other than to change trains, a break of journey at intermediate London Underground or DLR stations is not permitted.Īll tickets and travel are subject to the National Rail Conditions of Carriage. Tickets will only be accepted by London Underground and DLR up to the last day of validity of the ticket and until 04:29 the following day. between Liverpool Street and Paddington) by either London Underground, Docklands Light Railway (DLR) or Thameslink services as appropriate to the route of the journey being made. If the route shown on the ticket has a + or † symbol then the ticket includes the cost of travelling between certain London Stations (e.g. If you wish to change the date of travel, or the origin or destination of your ticket, it may be necessary to buy a new ticket and apply for a refund on your existing ticket (see Refund Policy below).Īnytime tickets can be used at any time but may require you to travel via a specific route or on a specific train company and this will be clearly stated on the ticket. In many cases, if you are still travelling at a time when your ticket is not restricted, no additional fare is payable. If you wish to change your time of travel you can pay the difference between the cost of the ticket held and the cost of the ticket that is most appropriate for the journey you need to make. The refund amount will normally take into account any use you have made of the ticket and in some circumstances no refund will be paid. You may be required to pay an administration fee (up to a maximum of £10 per ticket). If you decide not to use your ticket to make all or part of your intended journey then you can get a refund by returning your unused ticket to the ticket office or place of purchase (for tickets bought via websites, telesales or travel agents) within 28 days of the ticket expiry date.
