A representation of a network having vertices connected by arcs is provided. Different collections of vertices in the network are iteratively selected. Balancing moves are performed in corresponding collections of the network, where the collections are represented by corresponding graphs according to a predefined structure.

摘要:
A representation of a network having vertices connected by arcs is provided, where the network exhibits a pseudoflow. Arcs on which moves are to be performed are iteratively chosen for balancing excesses of vertices across the arcs until a stopping rule is satisfied. After the stopping rule is satisfied, further processing is performed to identify at least one of a minimum cut and/or maximum flow.
摘要:
To perform resource allocation in a system having plural tiers, one of plural resource allocation algorithms is selected in response to determining, based on one or more conditions, which of the plural resource allocation algorithms to select. The selected resource allocation algorithm is used to allocate resources for the plural tiers of the system.
摘要:
Fractional, non-integer numbers of servers are calculated for respective tiers of a multi-tiered system using a server allocation algorithm. The fractional, non-integer numbers of servers are rounded up to integer numbers to compute allocated numbers of servers for respective tiers.
摘要:
Plural sets of items corresponding to plural tiers of a multi-tiered system are defined, where the items represent amounts of resources to allocate to the tiers. Items from respective sets are selected based on a response time constraint and a target cost. Information is provided pertaining to allocation of amounts of resources to the respective tiers based on the selected items.
摘要:
A method of establishing a secure channel between a human user and a computer application is described. A secret unique identifier (“PIN”) is shared between a user and an application. When the user makes a request that involves utilizing the PIN for authentication purposes, the application renders a randomly selected identifier. The randomly selected identifier is in a format that is recognizable to a human but is not readily recognizable by an automated agent. The randomly selected identifier is then presented to the human user. The user identifies the relationship between the randomly selected identifier and the PIN. If the user's input reflects the fact that the user knows the PIN, then the user is authenticated.
摘要:
Software self-checking mechanisms are described for improving software tamper resistance and/or reliability. Redundant tests are performed to detect modifications to a program while it is running. Modifications are recorded or reported. Embodiments of the software self-checking mechanisms can be implemented such that they are relatively stealthy and robust, and so that it they are compatible with copy-specific static watermarking and other tamper-resistance techniques.
摘要:
Systems and methods are disclosed for embedding information in software and/or other electronic content such that the information is difficult for an unauthorized party to detect, remove, insert, forge, and/or corrupt. The embedded information can be used to protect electronic content by identifying the content's source, thus enabling unauthorized copies or derivatives to be reliably traced, and thus facilitating effective legal recourse by the content owner. Systems and methods are also disclosed for protecting, detecting, removing, and decoding information embedded in electronic content, and for using the embedded information to protect software or other media from unauthorized analysis, attack, and/or modification.
