The <~ rule defines an interface type - it indicates what properties are characteristic of a person and also gives type constraints on these properties. It documents that age is a functional property with an integer value, that lives is a unary relation over strings, and that dayOfBirth is a functional property with a value that is an object of ...
Productions (rules) are typically captured and defined by analysts and developers using some high-level rules language. They are collected into rule sets that are then translated, often at run time, into an executable Rete. When facts are "asserted" to working memory, the engine creates working memory elements (WMEs) for each fact
For a pair of types K, V, the type map[K]V is the type mapping type-K keys to type-V values, though Go Programming Language specification does not give any performance guarantees or implementation requirements for map types. Hash tables are built into the language, with special syntax and built-in functions.
The ten rules are: [1] Avoid complex flow constructs, such as goto and recursion. All loops must have fixed bounds. This prevents runaway code. Avoid heap memory allocation. Restrict functions to a single printed page. Use a minimum of two runtime assertions per function. Restrict the scope of data to the smallest possible.
PostScript originally required developers to manually reclaim memory using the save and restore operators. PostScript Level 2 introduced a garbage collector, but its usage is optional. [22] Rust supports optional reference counting, but manual memory management is preferred. Scala normally manages the memory automatically in its JVM and ...
If any updates have occurred, the store-conditional is guaranteed to fail, even if the value read by the load-link has since been restored. As such, an LL/SC pair is stronger than a read followed by a compare-and-swap (CAS), which will not detect updates if the old value has been restored (see ABA problem).
Bandwidth can be increasing by using large data bus path, data crossbar, memory interleaving (multi-bank parallel access) and out of order data transaction. The traffic can be reduced by using a cache that acts as a "filter" versus the shared memory, that is the cache is an essential element for shared-memory in SMP systems.
Though Go with Japanese ko rule is EXPTIME-complete, both the lower and the upper bounds of Robson’s EXPTIME-completeness proof [3] break when the superko rule is added. It is known that it is at least PSPACE-hard, since the proof in [ 2 ] of the PSPACE-hardness of Go does not rely on the ko rule, or lack of the ko rule.
