Function: replaceOptOutTopNModeler(uint256 _oldModelerIndex, address _newModeler, uint256 _medianPerformanceResults)

This function replaces a modeler in the topNModelers array with a new modeler based on their performance results.

Inputs

• _oldModelerIndex

  • Control: Controlled by the caller.

  • Constraints: Must be less than the length of the topNModelers array.

  • Impact: Identifies the index of the modeler to be replaced in the topNModelers array.

• _newModeler

  • Control: Controlled by the caller.

  • Constraints: N/A.

  • Impact: The new modeler to be inserted into the topNModelers array.

• _medianPerformanceResults

  • Control: Controlled by the caller.

  • Constraints: N/A.

  • Impact: The new index position of the _newModeler in the topNModelers array.

Branches and code coverage

Intended branches

• Validation of _oldModelerIndex.

  Test coverage

• Finding the new index for _newModeler based on _medianPerformanceResults.

  Test coverage

• Reordering of the topNModelers array and updating the modelerToMedian mapping.

  Test coverage

Negative behavior

• Revert if _oldModelerIndex is out of bounds.
