The present invention discloses a bit vector-based high-speed routing lookup apparatus and method, which mainly solves problems in the existing routing lookup methods that a data structure and a lookup operation are complex, hardware is hard to realize, and lookup speed is low. The apparatus includes a routing table coding module, a routing lookup module and an advanced coder module. The method includes the steps of ranking all routing table items stored in a routing table in a descending manner according to lengths of network prefixes; segmenting the routing table into multiple routing table blocks; converting the routing table blocks into bit vector arrays and storing the bit vector arrays in a memory; reading bit vector ''AND'' by bit in a corresponding sub address in the memory; and finding a routing table item matching with the longest prefix. The method has the advantages that the data structure and the lookup operation are simple, the hardware is easy to realize, and the lookup speed is high.

The invention is applicable to the field of biological medicine, and provides a method, device and equipment for generating an active peptide fragment and a storage medium, and the method comprises the following steps: obtaining a peptide fragment generation model corresponding to specific activity, the peptide fragment generation model is obtained by training an LSTM network by using a general peptide data set and a preset active peptide data set corresponding to the specific activity, the universal peptide data set comprises a plurality of universal peptide fragments; and generating a plurality of peptide fragments with specific activity by using the peptide fragment generation model. In the scheme, the peptide fragment generation model is obtained by training the LSTM network by using the general peptide data set and the preset active peptide data set corresponding to the specific activity, and can learn potential characteristics in the general peptide fragment and potential activity rules in the known active peptide fragment in the training process, so that the potential activity of the active peptide fragment is improved. Therefore, in the process of actually using the peptide fragment generation model, the peptide fragments with different specific activities and abundant diversity can be generated according to different specific activity requirements.

The embodiment of the invention discloses an information searching method and device, equipment and a storage medium. The method comprises the steps: when it is detected that a target user enters a target scene again, acquiring a historical display lookup table map generated when the target user enters the target scene again and enters the target scene last time; determining the actual searching frequency of each piece of to-be-searched information stored in a historical display searching table map generated when the target user enters the target scene every time, and adjusting the storage position of each piece of to-be-searched information in the historical display searching table map according to each actual searching frequency; and according to the adjustment result, generating a target display lookup table map, and finding out the information to be looked up required when the target user enters the target scene again from the target display lookup table map. According to the technical scheme, the information searching efficiency can be improved.

The invention discloses a method for quickly searching contacts based on edge touch. The method comprises the following steps: when detecting a sideslip touch signal, comparing a sideslip distance corresponding to the sideslip touch signal with a maximum sideslip distance threshold corresponding to each letter in a prebuilt associated alphabet one by one, so as to match a corresponding letter with the sideslip touch signal, wherein the letter is an initial letter of a contact name to be searched; and after that, updating the state of the associated alphabet and a currently displayed contact list according to the initial letter, so as to quickly enter the contact list to which the contact name to be searched belongs. According to the method for quickly searching the contacts based on the edge touch provided by the invention, the user does not need to slide ceaselessly from the first letter A until sliding to the contact list to which the contact name to be searched belongs, so that the search speed is improved and user experience is also improved. Correspondingly, the invention further provides a mobile terminal.

The invention provides an address table storage and lookup method, applied to a switch. The method comprises the following steps: receiving an address table query instruction; parsing the address table query instruction to obtain an Mac address and Vlan information to be looked up; querying a mapping address corresponding to the address table query instruction according to the Mac address and the Vlan information; and querying port information corresponding to the address table query instruction in a preset multi-layer chain table according to the mapping address, wherein the port information and the mapping address that corresponds to the port information are stored in the preset multi-layer chain table. The invention also provides an address table storage and lookup device, computer equipment and a readable storage medium. According to the invention, after an address table query instruction is received, the query instruction is parsed to acquire the Mac address and the Vlan information, the corresponding mapping address is queried, and the port information is queried in the preset multi-layer chain table to ensure that the retrieval for the Mac address and the Vlan information can be quickly performed, and the lookup speed can be increased.

The invention provides an information presentation manner change method and device. The method is applied to a terminal, and comprises the following steps of: obtaining a motion parameter of a card corresponding to a first information presentation manner on a terminal interface, wherein the motion parameter is generated when the card is moved, and the first information presentation manner is a card manner; judging whether the value of the motion parameter achieves a first type of preset parameter value; and when the value of the motion parameter achieves the first type of preset parameter value, converting the first information presentation manner into a second information presentation manner, wherein the second information presentation manner is a list manner. Through the method and device provided by the invention, the problem that the consumed time is long as a card type list is adopted to carry out rolling type search on content in the prior art is solved, and the search speed is improved.
