[1.7.0] - 2024-09-3

Changed

• rename the agent factories for clarity
• rename old basic_agent into deprecated_agent, as we are moving towards only using the entity_agent
• Moving supporting agents code to a more appropriate location
• Make terminators configurable for question of recent memories and set different default terminators for AvailableOptionsPerception (only for this one). This is needed because it often returns a list.
• Normalize rewards by the sum of positive relationships rather than number of players.
• Move LLM selection function used in python launch scripts to a utils file.
• Harmonize parameter name on ObservationSummary with other components.
• Remove variable that is no longer used in all_similar_memories component
• move agent components from component/agent/v2 folder to component/agent. Should also fix the problem introduced by moving old components to to_be_deprecated.
• Moving old agent components into a to_be_deprecated folder. Next CL will move components/agents/v2 into components/agents
• Update mistral wrapper to use latest version of mistral and fix langchain_ollama_model class name.
• Generalise somatic state and identity into an abstracted QuestionByQuery component
• Abstracting question based components into a parent class.
• Port two more legacy reflection components to the v2 entity component system.
• Port the legacy scheduled_hint component to the v2 entity component system
• Parameterize open_question to allow the user to change the labels Question and Answer.
• Improve mistral model wrapper with better error handling. Also added optional functionality to allow the use of different models for choice and text.
• Observation summary component in agent factories now summarizes a time interval that includes the latest timestep.
• adjust html making code to work best with new logging in agents
• Improve importance model.
• Prevent entity agents from continuing to talk beyond the end of a direct quote.

• improve prompts and logs for the entity agent and its components.
• Update options perception component to the entity component system.
• Add ComponentName typing annotation, instead of str, and improve docsctrings.
• update action spec, which now uses {name} instead of {agent_name}

[1.6.0] - 2024-06-11

Changed

• Reorganize modular launch files to better separate agent and environment concerns from each other, start reporting scores from all modular environments (printing them at the end of the run). Also, add a notebook to illustrate the new way of modularizing things. Also, various small improvements to all three modular environments, and use concurrency with better error handling in more places.
• Remove max_characters parameter on language model wrappers. It previously had different semantics from model to model, so it would have produced bugs if anyone was relying on it. It's better to remove it entirely since it's not needed.

• Reorganize Schelling diagram types and add get_scores function.
• Increase shared memory influence on output of formative memory generator.
• Improve inventory calculation prompt
• further improve conversations, especially handling of non-player characters
• Remove the confusing and hard to use 'adverb' parameter on the Plan component. Also rename plan timescale to horizon.

• Improve handling of improperly formatted generated formative memories.
• Make maximum conversation length configurable
• Make verbosity of conversation tracker configurable
• Only shutdown without waiting on error (better concurrent error handling)

Added

• Add players parameter to Inventory to fix a bug with supporting players and improve london esoteric market scenario.
• Fix a bug that arises with some completion models where the response to a specific quote processing thought in the game master sometimes ends up never terminating.
• Ensure completion models terminate when sampling for world background.

• Remove unused add_memory method on the basic_agent to simplify the API.
• Remove interrogation (legacy) API from basic agent.
• Clarify prompts in the all_similar_memories component.

• Add default importance and clock to blank memory factory (previous required).
• Add default importance function to associative memory (previous required).
• Improve the ollama model wrapper and refactor choice sampling for all LLMs.
• Allow the self perception component to have subcomponents.
• The delimiter symbol used to separate generated episodes in the formative memories generator is now configurable.

Previously the agent would not observe the conversation in that case since the usual way of observing the conversation happens in the conversation scene, which this approach bypasses.
• Fix bug which would cause a crash if no importance is passed in to memory.
• Fix bug in Schelling diagram payoffs component and refactor it.
• Fix bug in the Schedule component that adds 'None.' to memory when no events are scheduled on a given step.

[1.4.0] - 2024-05-15

Changed

Added

• Add aistudio model, remove deprecated cloud model, and rename vertex model.
• Add a debug language model that always returns empty strings and choice 0.

• fix typo

[1.3.0] - 2024-05-4

Changed

• Improve initialization of self perception component.
• Add configurable call_to_speech in conversation scene
• Change observation components to retrieve only observations from memory, filtering away memories produced by other components.
• Goal achievement and morality metrics trigger on action attempt rather than observation.
• Prevent the game master from inventing direct quotes
• Use new unstable attribute in pyink settings
• Add state lock and only update if the memory has changed.
• Replace tensorflow ST5 embedder with torch based one
• Support passing axis into plotting functions
• Fixing the call sequence in the apply_recursively and adding concurrency.
• Minor fixes to enable support of pandas 2.1
• Added len to associative memory, which returns the number of entries in the memory bank.
• Add clock to the plan component. It makes more sense when re-planning to know the time. Also, enables doing only one update per step
• Make sure components update only once per time step. Now that updates are recursively called on sub-components this makes a significant saving in API calls.
• Improve formative memories factory. Make more plausible memories.
• Make action_spec configurable per step
• Improve precision in the Inventory component.
• GM step function can optionally specify specific players to act this round.
• Skip updating dialectical reflection if already done on current timestep.
• More verbose uncertainty scale questions
• Improve error message for out of range timestamps (<1677 CE or >2262 CE).
• Encapsulate default game master instructions inside game_master class.
• Prevent adding duplicate memories
• Adding a check that makes sure the three questions components only updates once per time step
• increase max num tokens that can be produced by the direct effect component.

Added

• Add component that implements creative reflection
• Add customisation options for the conversation scene
• Add a current scene component to make the game master aware of the scene
• Adding the recursive component update to the game master, same logic as in the agent.

• Add updated ollama models
• Add scene runner and associated types
• Add example result obtained from running the three_key_questions colab.
• Add agent component to select all relevant memories
• Add relationships component that tracks the status of relationships between agents.

Also add the scheduled hint component which makes it possible to send specific text to a specific player when specific conditions are met.
• Add a function to create example question-answer pairs on an interactive document.
• Add optional thought functions to preserve direct quotes of agent speech.

Fixed

• Fix bug in 'all similar memories' component
