Scope is as main value (Q54828448): the property must be used by specified way only (Help)

List of violations of this constraint: Database reports/Constraint violations/P2159#Scope, hourly updated report, SPARQL

Type “algorithm (Q8366), solver (Q1966904)”: item must contain property “instance of (P31), subclass of (P279)” with classes “algorithm (Q8366), solver (Q1966904)” or their subclasses (defined using subclass of (P279)). (Help)

Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303).

Value type “computational problem (Q3435924)”: This property should use items as value that contain property “instance of (P31), subclass of (P279)”. On these, the value for instance of (P31), subclass of (P279) should be an item that uses subclass of (P279) with value computational problem (Q3435924) (or a subclass thereof). (Help)

Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303).

Label Change

In the property proposal for a "is solution to" property, we have discussed changing the label of this property to "computes solution to." As I state in that disucssion, the current label of P2159 is ambiguous because we say both "solution x solves problem z" and "method y solves problem z." If you object to relabeling this property, please share it here, otherwise I will make the change in a few days. — The Erinaceous One 🦔 10:06, 30 December 2020 (UTC)

Extend scope to hardware?

Application-specific hardware like GPUs, DSP, the new quantum chips (with all the code buried inside them) also compute specific jobs. Shouldn't they also be include here? Retired electrician (talk) 03:13, 19 December 2022 (UTC)

Could value be also Q1166625?

It's still something that can be solved. Martinligabue (talk) 14:30, 10 July 2023 (UTC)

Only specific mathematical problem (Q1166625). --Infovarius (talk) 20:07, 11 July 2023 (UTC)

violation

there's a violation at sorting algorithm (Q181593) which I've tried to fix but persists. I'd appreciate any pointers, please. Fgnievinski (talk) 20:49, 29 November 2024 (UTC)
