# OptimisticSolver

High-velocity solver requiring parallel runtime

Layer: Society · Category: Protocols

## Mechanism

A high-velocity implementation of [PolymorphicSolver](https://mindscape.world/scapes/bootstrap/PolymorphicSolver.md) designed for efficient multi-agent coordination. Requires a [Parallel](https://mindscape.world/scapes/bootstrap/Parallel.md) runtime (Actor Model with Mailboxes) to prevent serial deadlock. It explicitly couples the standard Solver lifecycle (Reason -> Solution) with the [AtomicBid](https://mindscape.world/scapes/bootstrap/AtomicBid.md) protocol. Unlike the base abstraction, this pattern MANDATES that the agent plan and execute in a single turn. It relies on [Reflexion](https://mindscape.world/scapes/bootstrap/Reflexion.md) and [Compensate](https://mindscape.world/scapes/bootstrap/Compensate.md) for error correction rather than pre-action permission. Use [ComputeBudget](https://mindscape.world/scapes/bootstrap/ComputeBudget.md) to bound resource consumption. Contrast with [RigorousSolver](https://mindscape.world/scapes/bootstrap/RigorousSolver.md) which prioritizes safety over speed. A [PathwayMemory](https://mindscape.world/scapes/bootstrap/PathwayMemory.md) accumulates across runs so the optimistic route-selection converges on strategies that historically succeeded under similar conditions.

## Invariants

- Turn Atomicity: Must output [BID] and [TOOL] in the same response.
- Non-Blocking: Cannot wait for Orchestrator approval on standard tasks.

## Preconditions

- Runtime supports Asynchronous/Parallel message delivery (Actor Model).
- Message Bus is non-blocking (Mailbox pattern).

## Failure modes

- Over-Eager Execution: Solving the wrong problem efficiently because feedback was skipped.
- Serial Deadlock: If deployed on a single-threaded (Talking Stick) engine, multiple atomic outputs will be dropped, halting the swarm.

## Caution

Executes without pre-action verification. Ensure irreversible actions have compensation or sandboxing, or use RigorousSolver at those boundaries.
