Load Objectives

Loads optimization objectives for a trial in globalMOO.

Endpoint

POST /models/{model_id}/projects/{project_id}/trials/{trial_id}/objectives

Path Parameters

Parameter	Type	Required	Description
model_id	integer	Yes	ID of the model
project_id	integer	Yes	ID of the project
trial_id	integer	Yes	ID of the trial

Request Parameters

Parameter	Type	Required	Description
objectives	array[float]	Yes	Target values for each objective
objectiveTypes	array[string]	Yes	Type for each objective (see below)
initialInput	array[float]	Yes	Initial input values (must match project input count)
initialOutput	array[float]	Yes	Initial output values (must match objectives count)
desiredL1Norm	float	Yes	Desired L1 norm for objectives (default: 0.0)
minimumBounds	array[float]	Conditional	Lower bounds (required for percent/value types)
maximumBounds	array[float]	Conditional	Upper bounds (required for percent/value types)

Objective Types

Valid objective types are:

• exact - Match target value exactly within L1 norm

• percent - Within a percentage range of target value (requires bounds)

• value - Within an absolute range of target value (requires bounds)

• lessthan - Less than target value

• lessthan_equal - Less than or equal to target value

• greaterthan - Greater than target value

• greaterthan_equal - Greater than or equal to target value

• minimize - Find minimum possible value

• maximize - Find maximum possible value

Error Responses

Status Code	Description
400	Invalid request - Missing required fields, invalid format, or validation errors
401	Unauthorized - Invalid API key
404	Model, project, or trial not found
429	Too many requests - Rate limit exceeded
500	Internal server error

Server-Side Validation

The API performs the following validations:

• Model, project, and trial IDs must be positive integers

• Array lengths must be consistent:

  • objectives and objectiveTypes must have the same length

  • initialInput length must match the project's input count

  • initialOutput length must match objectives length

  • minimumBounds/maximumBounds must match objectives length when required

• All numeric values must be valid floating point numbers

• Objective types must be valid types as listed above

• For percent and value objectives:

  • minimumBounds and maximumBounds are required

  • maximumBounds values must be greater than minimumBounds

• desiredL1Norm must be provided and non-negative (defaults to 0.0)

• Trial must exist and be in an active state
