Description

When requesting for tasks, the caller can determine the number of Validators that validate the generations.

The validation process is done using the Standard deviation method, where the values that are far from the mean are ignored.

And the score for a given generation is given by the average of the scores make by validators.

The problem is That the Standard Deviation method, is not a checking mechanism to validate a small number of inputs, validating one input is non-sense, as this single validator can give any score to any generation, and no one will catch him.

So in case we have 5 generations and 1 validator, and there are 1 Generator OutLier. The validator can make scores for the valid generations' mad ones, and the outlier gives him the ideal score allowing him to prevent honest generators from their rewards, as well as hurting BuyerAgent by giving the wrong response to him.

Oracles are accessible to anyone, and the Validation process is made to reach what is like a consyses and detect outliers, but accepting 1 validator will make the validation process inactive, and the 2 validations also can be ineffective a all.

Recommendations

Make the number of validations either 0 if no validations, or in case of accepting validations, accept only 3 or higher.
