Space Economy Driver Implication Chain
Build space-economy driver chains and report their maximum length and any cycle encountered.
Description
Space-economy implications can be represented as one-successor driver chains.
Space-economy implications can be represented as one-successor driver chains. A cycle and the absence of a starting root are distinct graph properties.1
The returned values include Driver chains, Cycle detected, Maximum chain length. The How section below explains the calculation, input rules and interpretation.
When to use Space Economy Driver Implication Chain
Use Space Economy Driver Implication Chain when you need to evaluate the supplied records under the calculation and evidence rules below. No real space-economy causation is established; maximum length includes an appended repeated node.
Define the question, evidence and scenario assumptions first. Supply the chosen score scales, time horizons or reference selection explicitly. Interpret generated text as a discussion template and screen labels as the stated rules.
How to use Space Economy Driver Implication Chain and understand its results
- Define the question, evidence and scenario assumptions first. Supply the chosen score scales, time horizons or reference selection explicitly. Interpret generated text as a discussion template and screen labels as the stated rules.
- Enter driverIds, nextDriverIndices using the field table and calculation rules, then run the tool.
- Read chains, cycleDetected, maximumChainLength. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| driverIds | Driver IDs | list of string | Required |
| nextDriverIndices | One -1 terminal marker or valid next-driver index per driver. | list of number | Required |
Require aligned nonempty unique trimmed nonblank IDs and safe-integer next indexes −1 or within range. Scan all components for cycles. Build chains only from roots; append the repeated node before stopping a cycle. Return chains, cycle flag and maximum printed path length. For a pure cycle the calculation has no root-based chains and computes maximum length zero; the output contract requires at least one, so the executed tool reports an invalid-output input issue instead of returning a cycle result.
roots=nodes never targeted by next indices Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| chains | Driver chains | list of string |
| cycleDetected | Cycle detected | boolean |
| maximumChainLength | Maximum chain length | integer; minimum: 1 |

}Limitations and assumptions
No real space-economy causation is established; maximum length includes an appended repeated node.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Core numeric and string lists are limited to 100,000 entries; text entries are subject to the general large-text limit. Follow any smaller calculation limits above. Missing fields without a declared default, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
Alternative or Complementary methods
Use Connectivity Everywhere Driver Chain Builder: Connectivity implications can be represented as one-successor driver chains. Root-based paths and cycle detection expose the structure of caller-supplied links. For a complementary task, use Energy Transition Driver Implication Chain: Energy-transition implications can be represented as one-successor driver chains. Root-based paths and cycle detection expose the structure of caller-supplied links.
